• Dmitri Ivanovich Mendeleev
• 1834-Born in Tobolsk, Western Siberia
• Youngest of 14 children
• Graduated from Central Pedagogic Institute in St.
  Petersburg
• From Royal Chemical Society

4
Before Mendeleev

• 1789 Antoine Lavoisier defines chemical element
• Lavoisier created a table for 33 elements
• Classified as gases, nonmetals, metals, and
  earths
• Royal Chemistry Society

5
Mendeleevs Breakthrough

• I began to look about and write down the
  elements with their atomic weights and typical
  properties, analogous elements and like atomic
  weights on separate cards, and this soon
  convinced me that the properties of elements are
  in periodic dependence upon their atomic
  weights. --Mendeleev, Principles of Chemistry,
  1905, Vol. II

Mendeleevs Genius

• Elements follow a natural order
• When the elements are arranged according to
  increasing mass, the chemical properties of the
  atoms form a pattern.

7
Mendeleevs Genius

• Mendeleev recognized there were undiscovered
  elements.
• By using his periodic table, he could predict the
  chemical properties of the undiscovered elements.

8
Initial Publications

• In March 1869, Mendeleev presented a paper to the
  Russian Chemical Society entitled On the
  Correlation Between the Properties of the
  Elements and their Atomic Weights
• Not translated from Russian until 1895
• Mendeleev on the Periodic Law p.11

9

• In 1869, two German abstracts of the paper were
  published.
• The first contained only the table.
• The second failed to mention the word periodic
  and contained a confusing typographical error.
• Mendeleev on the Periodic Law p.11

Competition

• Mendeleev was recognized as the first scientist
  to publish on the relationship between atomic
  weight and periodic chemical properties.
• Second place went to German chemist, Julius
  Lothar Meyer, who created a table of the elements
  and published a paper in December 1869.

11
Recognized by Nobel Scientists

• He did not win the Nobel Prize (One source said
  he was only one vote from winning)
• However, he was mentioned by scientists in 8
  Nobel Lectures including the lectures of Marie
  Curie, Niels Bohr, and Otto Hahn.

The Beauty of the Periodic Table

• On learning about the table For the first
  time I saw a medley of haphazard facts fall into
  line and order. All the jumbles and recipes and
  hotchpotch of the inorganic chemistry of my
  boyhood seemed to fit themselves into the scheme
  before my eyes as though one were standing
  beside a jungle and it suddenly transformed
  itself into a Dutch garden. C.P. Snow
  (Scientist and author)

More Recognitions

• Element 101, Mendelevium (Md)
• Asteroid No.2769 Mendeleev (period 5.55 years)
• Russian Scientific Ship Dmitriy Mendeleev
• From Moscow State University

18
Other Russian Contributions to the Periodic Table

• Joint Institute for Nuclear Research established
  in 1956 in Dubna, Russia
• Element 105 is named Dubnium to recognize the
  distinguished contributions to chemistry and
  modern nuclear physics of the international
  scientific center.

• Includes
• Atomic symbol
• Atomic mass
• Atomic number
