سيرته

ولد دميتري ايفانوفيتش منديلييف في 27 يناير( 8 فبراير حسب التقويم اليولياني القديم) عام 1834 بالقرب من توبولسك في سيبيريا. وكان دميتري الطفل السادس عشر والاخير للأب إيفان بافلوفيتش مندليف " Ivan Pavlovich Mendeleyev" والأم ماريا ديمتريڤنا مندلييڤا (وكان لقبها قبل الزواج كورنيلييڤا) " Maria Dmitrievna Mendeleeva (nee Kornilieva)". علما ان ثمانية منهم فارقوا الحياة في سن الطفولة. وفي سن الرابعة عشر، بعد موت والده, إلتحق مندليف بالجيمنازيوم فى توبولسك.

وفى عام 1849، إستقرت عائلة مندليف الفقيرة فى سان بطرسبرج, حيث إلتحق بالمعهد التربوي العالي فى عام 1850. وبعد التخرج, أصيب بالسل مما جعله ينتقل إلى شبه جزيرة القرم على البحر الأسود فى عام 1855، حيث أصبح الرئيس العام للعلوم فى المدرسة الثانوية المحلية. ثم إستعاد صحته ورجع إلى سان بطرسبرج عام 1856.

وفى الفترة من 1859 إلى 1861 عمل فى كثافة الغازات فى باريس., وأعمال المطياف مع جوستاف كيرشوف " Gustav Kirchhoff" فى هايدلبيرج. وفى عام 1863, وبعد رجوعه إلى روسيا, أصبح مدرس الكيمياء فى المعهد التقني وفى جامعة سان بطرسبرج. وفى نفس العام, تزوج من فيوزڤا نيكيتشنا لشيڤا " Feozva Nikitichna Leshcheva". ثم أعجب بأنا إيڤانوڤنا پوپوڤا ولاحقها وهددها بأن ينتحر إن لم توافق على الزواج منه. فقبلت وتزوجته قبل شهر من انتهاء اجراءات طلاقه من زوجته الأولى. وقد تزوجت إبنته من زوجته الأولى من الشاعر الروسي المشهور ألكسندر بلوك " Alexander Blok".

وبالرغم من أن مندليف تم تكريمه من كل المؤسسات العلمية فى أوروبا، بما فيها حصوله على وسام كوپلي من الجمعية الملكية في لندن, فإن نشاطه السياسي كان يقلق الحكومة الروسية، مما أدى لإقالته من جامعة سانت بطرسبرج فى 17 أغسطس عام 1890. وفي عام 1893، تم تعيينه مدير لديوان الأوزان والقياسات.

وفى سنواته الأخيرة, عمل خارجه وإخترع المواصفات القياسية للڤودكا " vodka" الروسية. وأكثر أهمية من ذلك قام بالتحقق من حقول وتركيب النفط. وساعد فى عمل أول مصفاة زيت فى روسيا. وقد توفي في سانت بطرسبرج بسبب الإنفلونزا. وتم تسمية العنصر رقم 101, مندليفيوم بإسمه.

الجدول الدوري
One form of Mendeleev's periodic table, from the 1st English edition of his textbook (1891, based on the Russian 5th edition)
الجدول الدوري للعناصر

ثمة معلومة خاطئة شائعة مفادها أن منديلييڤ رأى جدوله في الحلم. بيد أن الأمر ليس كذلك. فإن الجدول الدوري هو ثمرة عمل استمر اعواما طويلة. وأجاب منديلييف مرة حين سألوه حول كيف اكتشف الجدول الدوري بقوله: "إنني ربما فكرت فيه طوال عشرين عاماً، بينما تعتقدون أنني جلست .. وفجأة كان كل شيء جاهزاً".

في عام 1866, نيولاندز " John Alexander Reina Newlands" قام بنشر نظرية الثمانيات. ولكن عدم وجود فراغات كافية للعناصر التى لم يتم إكتشافها, وتواجد بعض العناصر فى نفس الخانة كانت من الإنتقادات الموجهة لهذ النظرية، وبالتالى لم يتم قبولها. وبإغفال هذا، قام مندليف بالعمل على فكرة مشابهة، وفى 6 مارس 1869، تم تقديم الشكل الأساسي لها للجمعية الروسية للكيمياء، بعنوان "العلاقة بين خصائص العناصر وأوزانها الذرية" ، والتى نصت على أن:
Cl 35.5 K 39 Ca 40
Br 80 Rb 85 Sr 88
I 127 Cs 133 Ba 137
تمثال لتكريم مندلييف والجدول الدوري، في براتيسلاڤا، سلوڤاكيا.
تمثال في سانت بطرسبرگ.


1. لو تم ترتيب العناصر طبقا لوزنها الذري فإن خصائصها تتكرر دوريا.
2. العناصر المتشابهه فى خواصها الكيميائية لها أوزان ذرية إما قريبة من بعضها (مثل Pt, Ir, Os) أو تزيد بإنتظام مثل (K, Rb, Cs).
3. ترتيب العناصر, أو مجموعة من العناصر حسب أوزانها الذرية, يتفق مع ما يسمي التكافؤ, وأيضا, إلى درجة ما، إلى خواصهم الكيميائية المميزة, كما يظهر بوضوح فى سلسلة Li, Be, Ba, C, N, O, Sn.
4. العناصر المنشرة بكثرة لها أوزان ذرية صغيرة.
5. تحدد قيمة الأوزان الذرية صفات العنصر, كما أن قيمة الجزيء تحدد صفات المركب.
6. يجب توقع إكتشاف عديد من العناصر الغير مكتشفة وقتها مثلا عنصر مشابه للألومنيوم والسيليكون – والذى يتوقع له وزن ذري بين 65 و 75.
7. يمكن ضبط الوزن الذري للعنصر بمعرفة الأوزان الذرية للعناصرالملاصقة له. وعلى هذا يكون الوزن الذري لعنصر التيلوريم يجب أن يكون بين 123 و 126 ولا يمكن أن يكون 128.
8. يمكن توقع خواص معينة للعناصر طبقا لوزنهم الذري.

وكان لوثر ماير غير المعروف لمندليف يعمل أيضا على الجدول الدوري. وفى بحثه المنشور عام 1864, قام ماير بعض 28 عنصر فقط, مقسمين حسب تكافؤهم وليس حسب وزنهم الذري. ولم يكن عن عند ماير أى فكرة عن توقع العناصر الغير موجودة أو تصحيح الأوزان الذرية للعناصر الموجودة. وبعد أشهر قليلة من نشر مندليف لجدوله لكل العناصر المعروفة وقتها (وتوقعه عديد من العناصر التى سوف تكمل الجدول الدوري, بالإضافة لتصحيح بعض الأوزان الذرية), قام ماير بنشر صورة مطابقة للجدول، على الرغم من توقعات مندليف الدقيقة لما سماه تحت-سيليكون (جرمانيوم), تحت-ألومنيوم (جاليوم), تحت-بورون (سكانديوم) أعطاه نصيب الأسد فى الجدول الدوري. وبأى حال, فإنه فى وقت عرض توقعات مندليف فإنها أثرت بشدة على كل زملاؤه وإتضح صحتها بعد ذلك.

اكتشف منديلييف في فبراير عام 1869 لدى تأليف " اصول الكيمياء" احد قوانين الطبيعية الرئيسية – القانون الدوري للعناصر الكيميائية ( يسود الاعتقاد في الغرب ولاسيما في المانيا ان لوتار ماير توصل الى هذا الاكتشاف ايضا). ان الاختلاف الكبير بين هذين الجدولين يكمن في ان جدول ماير هو أحد صيغ تصنيف العناصر الكيميائية المعروف في ذلك الزمن ، اما الخاصية الدورية التي اكتشفها منديلييڤ فتمثل منظومة قادت الى ادراك الحتمية التي اتاحت تحديد مكان العنصر فيها – والتي لم تكن معروفة آنذاك، والتنبؤ ليس فقط بوجود العنصر بل تحديد

Periodic tableone form of mendeleev's periodic table, from the 1st english edition of his textbook (1891, based on the russian 5th edition)
periodic table of elements

There is information common misconception that Mendalaaڤ saw in a dream schedule. However, it is not.The periodic table is the result of long-continued for years. And Mendeleev answered once when asked about how discovered the periodic table, saying: "I probably thought about it for twenty years, while you think I sat down .. and suddenly everything was ready."

In 1866,Newlands "john alexander reina newlands" The publish theory eighties. But the lack of adequate spaces for elements that have not been discovered, and the presence of some elements in the same box was one of the criticism Lhz the theory, and therefore not be accepted.And بإغفال this, the Mendeleev working on similar idea, and in the March 6, 1869, was presented the basic shape her Assembly Russian Chemistry, entitled "The relationship between the properties of the elements and their atomic weights," which stipulates that:
cl 35.5 k 39 ca 40

1. If the items have been arranged according to the weight of the atomic characteristics recur periodically.
2.Arrangement of elements, or a combination of elements according to their atomic weights, consistent with the so-called parity, and also,Elements frequently sawmill have small atomic weights.
5. The value of atomic weights recipes element, and the molecule value that determines the characteristics of the boat.
6.Should expect the discovery of many Unusual Items discovered at the time, for example, an item similar to aluminum and silicon - which is expected to atomic weight between 65 and 75.
7. Can adjust the atomic weight of the element by the atomic weights for his Anasralamlasqh.And this is the atomic weight element التيلوريم must be between 123 and 126 can not be 128.
8. Can be expected of certain properties of the elements according to their weight atomic.

Luther was Meyer is known for Mendeleev also works on the periodic table.In his research, published in 1864, Meyer has only some 28 element, divided by reward and not according to their atomic weight. It was not for when Meyer any idea of ​​the expected elements of non-existent or correct atomic weights of existing elements.A few months after the publication of Mendeleev to schedule all the elements known at the time (and expect many of the elements that will complement the periodic table, as well as to correct some of the atomic weights),Mayer has published a picture identical to the table, despite the expectations of Mendeleev minute of what he called under - silicon (germanium), under - aluminum (Jaleom), under - boron (scandium) gave the lion's share in the periodic table. In any case,It at the time of display Mendeleev expectations they strongly influenced both his colleagues and then it turns correctness.

Mendeleev discovered in February 1869, has authored "Chemistry assets" one of the main natural laws - periodic law of chemical elements (It is widely believed in the West, especially in Germany, Lothar Meyer to reach this discovery too).The big difference between the two lies in the tables that the agenda Meyer is a form of classification of chemical elements known at that time, either the property discovered by rotating Mendalaaڤ represents the system led to the inevitable realization that allowed locateWhere - and which were not known at the time, and predict not only the presence of the element but to identify

2. Similar items in chemical properties have atomic weights either close together (such as Pt, Ir, Os) or regularly (such as K, Rb, Cs)
3. The order of the elements, or a collection of items by atomic weights, in accordance with the so-called parity, and also, To some degree, to the chemical attributes, as is clearly shown in the series of Li, Be, Ba, C, N, O, Sn.

7. You can adjust the atomic weight of the element with atomic weights llanasaralmlaskh. The atomic weight of an element altilorim must be between 123 and 126 can't be 128.
8. Certain properties can be expected for the elements according to their Atomic

and Luther Mayer is known as lmandliv also works on the periodic table. In his research, published in 1864, the Meyer some 28 element only, divided according to their equivalence, not by their weight. And not from when Meyer any idea of the expected elements of others exist or correcting atomic weights of the elements. And a few months after Mendeleev published the schedule for all elements known at the time (and expect several items that will complete the periodic table, as well as to correct some atomic weights), The Meyer published the picture match the table, despite predictions of Mendeleev so-called under-Silicon (germanium), under-aluminum (gallum), under-boron (scandium) gave him the lion's share of the periodic table.

In spite of the مندليف was honoring of all scientific institutions in Europe, including getting the Medal of كوپلى of the Royal Society in London.Political activity was concerned, the Russian government, which resulted in his sacking of the University of St. Petersburg on 17 august 1890. In 1893, he was appointed director of weights and measurements.

in recent years.The work of the outside invented standard specifications للڤودكا " vodka" Russian.

Periodic Table of Elements common

there is false information that منديلييڤ view his schedule in the dream. However, that is not the case.The periodic table is the result of the long years. Mendeleev once again responded when asked about how to find out the periodic table, saying: "I might have thought about it over 20 years, while you think I sat .. And suddenly everything was ready" .

in the year 1866,Newlands " John Alexander Reina Newlands" published by the theory of the octets. But the lack of adequate inventory of elements that have not been discovered, and the presence of some elements in the same box was of criticisms against this theory, therefore, not be accepted.The Islanders, The مندليف to work on the idea of similar, on March 6 1869, was to provide basic form a Russian assembly chemistry, entitled "The relationship between the characteristics of the elements, their weighting Agency", which stipulates that:

1. If the arrangement of elements according to her weight atomic radiation, their characteristics are repeated periodically.
2.Typical elements in chemical properties of atomic weight as close to each other (such as PT, IR, OS) or increase regularly (such as K, RB, CS) .
3. The arrangement of elements, or a group of elements by atomic weight, in accordance with the so-called parity, as well as,To some degree, to the attributes of chemical, as clearly appears in a series of LI, Be, BA, C, N, O, SN.
4. Sawmill elements commonly have small atomic weight.
5. Determine the value of the atomic weight characteristics of the component, and that the value of the particle determine the characteristics of the boat.
6.It should be expected the discovery of several elements, for example, then the unexplored element aluminum similar silicon - which is expected to atomic weight between 65 and 75.
7. atomic weight component can be adjusted by atomic weights للعناصرالملاصقة him.And this be atomic weight التيلوريم component must be between 123 and 126, and can be 128.
8. can be expected to specific features of the elements according to atomic لوزنهم.

Luther Meyer was not known لمندليف also work on the periodic table.In his research published in 1864, The Meyer some 28 element only, divided by تكافؤهم and not according to atomic weight. It was not the When Mayer any idea of the elements that are expected or correct existing elements of atomic weights.After a few months of deployment of مندليف calendar for each known elements at that time (and anticipate many of the elements which would complement the periodic table, as well as to correct some atomic weights),The Mayer Image Deployment in conformity with the schedule, in spite of expectations مندليف per minute for what he called under-silicon (جرمانيوم), under-aluminum (جاليوم), under-boron (سكانديوم) gave lion's share on the periodic table. In any case,It was in at the time of the introduction of expectations مندليف it strongly affected the health revealed all his colleagues after that.

Discover the Mendeleev in february 1869 to form a " assets of chemistry" one of major natural Laws - the law of chemical elements ( belief prevails in the West, especially in Germany, Lothar Meyer reached to this discovery also).The significant difference between these two tables that lies in the fact that the Agenda Mayer is one of formulas for the classification of chemical elements known at that time, the periodic feature discovered by منديلييڤ unallocated led system to recognize imperative which allowed the place- which was not known at that time, and Forecasting is not only the presence of the component, but the
