DMITRI IVANOVICH MENDELEEV

He was born in Russia

in 1834

He always tried to be the best that he

could be,And chose to make

his mark in chemistry.

Dmitri Ivanovich Mendeleev was his full name

Born in Tobolsk, Siberia, Russia

He was a Russian chemist

Born on February 8, 1834

Parents were Ivan Pavlovich Mendeleev and Maria Dmitrievna Kornilieva

Mendeleev died on February 2, 1907

Studied at St. Petersburg and graduated in 1856

After graduating from St. Petersburg he was appointed to a professorship

Three years after being appointed to a professorship he succeeded to the chair in the University

He was considered one of the greatest teachers of his time

Davy Medal from Royal Society of England in 1882

Domindov Proze for his book "Organic Chemistry"

Copley Medal from the Royal Society of England (its highest award) in 1905

In 1893, he was appointed the Director of the Bureau of Weights and Measures.

In 1905 Dmitri Mendeleev was elected a member of the Royal Swedish Academy of Sciences.

The crater Mendeleev on the Moon, as well as an element number 101, the radioactive Mendelevium, are named after him.

Dmitri Mendeleev wrote the definitive two-volume textbook ‘Principles of Chemistry’ (1868-1870).

Dmitri Ivanovich Mendeleev is the creator of the first version of the Periodic Table of Elements. Using the table, he predicted the properties of elements yet to be discovered.

He investigated the heat expansion of liquids, and devised a formula similar to Gay-Lussac's law of the uniformity of the expansion of gasesHe investigated the composition of oil fields, and helped to found the first oil refinery in Russia. He formulated new state standards for the production of vodkaHe invented pyrocollodion, a kind of smokeless powder based on nitrocellulose.

He wondered if Naturereally had a masterplan, If the elementshad a pattern that onecould understand.

So he bought a bunch ofcards and on each onewrote the name of anelement and itsweight, and then heplayed the game.

He put them all in order by their

atomic weights, used their chemical

properties to differentiate.

Groups began to form and despite some

question marks, he managed to produce

a simple periodic chat.

At first in 1869 thechart was not a hit,

but that young Russianchemist was not thekind to quit.

He revised atomicweights and stayedhis whole career,

predicting that severalnew elements wouldappear.

A few years passed and sure enough

they came, Gallium, scandium,

germanium were their names.

Chemists everywhere were impressed

with what they saw

So they call him the father of the periodic table, and his work gave rise to another kind of label.It’s the name for element number 101,in honor of this man they call it Mendelevium.
