Dmitri Mendeleev was a Russian chemist born in 1834 who is considered the father of the periodic table. He arranged the known elements in his 1869 periodic table based on their atomic mass, with spaces left for elements not yet discovered, enabling him to predict some of their properties. Some of his major works include his textbook The Principles of Chemistry and his development of the periodic table established the basis for organizing the chemical elements that remains in use today.

Europe, including (in 1882) the Davy Medal from the Royal Society of
London (which later also awarded him the Copley Medal in 1905), he
resigned from Saint Petersburg University on 17 August 1890.

7. contributions • Dmitri Mendeleev was a Russian
chemist who lived from 1834 to 1907.
He is considered to be the most
important contributor to the
development of the periodic table. His
version of the periodic table organized
elements into rows according to their
atomic mass and into columns based
on chemical and physical properties.

8. Early periodic
table
• The periodic
table was arranged by atomic
mass, and this nearly always
gives the same order as the
atomic number. However, there
were some exceptions (like iodine
and tellurium, see above), which
didn't work. Mendeleev had seen
that they needed to be swapped
around, but it was Moseley that
finally determined why.

9. Firstperiodictable
• In 1869 Russian chemist Dimitri Mendeleev
started the development of the periodic
table, arranging chemical elements by
atomic mass. He predicted the discovery of
other elements, and left spaces open in his
periodic table for them. In 1886 French
physicist Antoine Becquerel first discovered
radioactivity.

10. Mendelevium
• Mendeleev is a synthetic element
with the symbol Md and atomic
number 101. It was named after
Dmitri Mendeleev, father of the
periodic table of the chemical
elements. Using available
microgram quantities of the
isotope einsteinium-253, over a
million mendelevium atoms may
be produced each hour.
