define mendeleev's periodic table......... ​

Answer 1

$\huge\star{\green{\underline{\mathfrak{Answer!!}}}}$

In 18690 Russian chemist Dmitri Mendeleev Published a Periodic Table and corresponding periodic law of 63 elements known at that time

Mendeleev’s Periodic Law states that “The Physical and Chemical Properties of the elements are periodic functions of their atomic weights.”

Definition Of Mendeleev?S Periodic Table

Mendeleev’s Periodic Law states that “The Physical and Chemical Properties of the elements are periodic functions of their atomic weights.”

More About Mendeleev’s Periodic Table

Mendeleev created a periodic table by listing elements in a row in order of atomic weight and starting a new row the characteristics of element began to repeat

This resulted in arrangement where the element with similar properties occupies the same vertical column

Mendeleev called these vertical columns as Groups and resultant horizontal rows as Series

Mendeleev success roots to his vision of classification of elements based on similarities in their empirical formulas and properties of compounds formed by them

This made him to occasionally ignore the order suggested by atomic weights to classify elements with similar properties together

Answer 2

Mendeleyev is best known for his discovery of the periodic law he adopted in 1869 and the periodic table of elements he developed. He died on February 2, 1907, in St. Petersburg, Russia.

Among chemical properties, Mendeleev treated formulae of hydrides and oxides as one of the basic criteria for categorization. He took 63 cards and on each card, he wrote the properties of one element. He grouped the elements with similar properties and pinned it on the wall. He observed that elements were arranged in the increasing order of atomic mass and there was the periodic occurrence of elements with similar properties.

According to this observation, he formulated a periodic law which states:

“the properties of elements are the periodic function of their atomic masses.”
