Question

what was the two criteria used by mendeleev in creating his periodic. table

Answer 1

Answer:

Mendeleev used atomic mass of the elements as the unique criteria of the elements. He proposed that the chemical properties of elements are the periodic function of their atomic masses. And thus, he arranged the elements in the increasing order of their atomic masses.

Answer 2

Mendeleev was a Russian chemist and inventor. He proposed two characteristics while creating his periodic table.

1- Increasing atomic masses of the elements.

2- Elements with similar chemical properties were placed in a group.

He suggested that the properties of the elements are periodic functions of their atomic masses. This was known as periodic law. The arrangement of the elements in increasing order was called a periodic table.
