Question

What is atomicity ? explain with two examples

Answer 1

Atomicity :

Atomicity denotes to the number of atoms present in a single molecule of an element, substance or compound.

It can also be considered as the nature of molecules.

Atomicity cannot be broken into further small portions.

According to atomicity of a substance, the atomicity can be Mono, Di, Tri and Poly.

Example of atomicity :O2 is a Diatomic substance which has 2 atoms.

Answer 2

DEFINITION :-

Atomicity of a molecule is the number of atoms present in that molecule .

EXAMPLE :-

1. 2H2 + O2 --> 2H2O

Two molecule of hydrogen react with one molecule of oxygen to form two molecules of water. Each molecule of hydrogen has two atoms of hydrogen, the atomicity of hydrogen is 2.

2. O2

there are 2 atoms of oxygen so atomicity is 2
