Question

Mention the factor on which the chemical properties of elements depend.​

Answer 1

Explanation:

The chemical properties of an atom depend upon the atomic number. From atomic number we can get valence electrons that determines the chemical properties of it.

Answer 2

modern periodic table states that :-Properties of elements are periodic function of their atomic number

so chemical properties also depends on atomic number which depends on number of electrons and protons present in the atom of it's elements

So finally chemical properties of an element depends upon it's valency or valence electrons
