Answer 2

Answer:

Explanation:

(i) The atomic number of an element indicates the

number of protons in the nucleus or the number

of electrons in the atom.

(ii) All the atoms of an element have the same atomic

number.

(iii) The number of electrons present in the outermost

shell of an atom is responsible for the formation

of compounds either by sharing, accepting or

donating electrons.

(iv) The chemical properties of an element are decided

by its atomic numbers. Hence, atomic number is a

more fundamental property of an element than its

atomic mass.
