Question

Classify each of the following on the basis of their atomicity

$\left(a\right)F_2\left(b\right)O_3\left(c\right)S_8\left(d\right)\mathrm{He}\left(e\right)P_4\left(f\right)\mathrm{Mg}\left(g\right)N_2$

Answer 1

The atomicity of a molecule is defined as the total number of atoms present in that molecule. On the basis of atomicity, molecules can be classified as:
1. Monoatomic molecules - Contain one atom
2. Diatomic molecules - Contain two atoms
3. Triatomic molecules - Contain three atoms
4. Polyatomic molecules - Contain more than three atoms

Therefore, the molecules given in the question can be classified as follows:

Monatomic	Diatomic	Triatomic	Polyatomic
He, Mg	F2 , N2	O3	S8 , P4
