A Russian chemist named Dmitri Mendeleev wrote it and this periodic table was a table to illustrate recurring trends in the properties of elements.
Dmitri Mendeleev figured out that there were missing elements on his periodic table. Using periodic trends and averaging numbers, he could make pretty accurate predictions about elements not discovered yet. Mendeleev predicted four: * ekaboron (modern day scandium) * ekaaluminium (modern day gallium) * ekamanganese (modern day technetium) * ekasilicon (modern day germanium)
Mendeleev stated on his periodic table that: If the elements are arranged according to their atomic mass, a pattern can be seen in which similar properties occur regularly.

Dmitri Mendeleev was a Russian chemist who is famous for formulating the periodic table of elements, arranging them according to definite trends in their properties. He was born in 1834 and died in 1907.
In 1869, a Russian chemist named Dmitri Mendeleev invented this table to help show trends in the behavior of chemicals.

A lot of people noticed similar trends, but it took Dmitri Mendeleev to organise them by increasing atomic number and group them by similar characteristics.
