Question

how to find atomicity​

Answer 1

Atomicity of an element is a measure of the total number of atoms present in a molecule

. For example, an oxygen molecule (written as O2) consists of 2 atoms of oxygen (O) and hence an atomicity of 2. Similarly, an ozone molecule (O3) consists of 3 atoms of oxygen and has an atomicity of 3.

There is a simple way to

determine the atomicity of any element. It can be determined as a ratio of molecular mass and atomic mass.

For example, using the case of oxygen molecule, the molecular mass is 32 (= 2x16), while the atomic mass is 16. If we divide the two, we get atomicity as 2 (=32/16).

Answer 2

Explanation:

It can be determine as a ratio of molecules mass and atomic mass.
