This is your answer and mark me as a brainlist pls

Explanation:

Atomicity is the total number of atoms present in a molecule of an element or compound. For example Ozone(O3) has 3 oxygen atoms. So it's atomicity is 3.

Monoatomic- consists of one atom. Example-Na,K,Ne etc

Diatomic- Consists of two atoms. Example-O2,N2,H2 etc

Triatomic- Consists of three atoms. Example- O3

Polyatomic- Consists of more than 3 atoms. Example- P4, S8 etc

Hydrogen(H2)- 2

He - 1

Li- 1

Be- 1

B - It has Allotropes

C-2,4

N2– 2

O2– 2

F2- 2

Ne- 1

Na- 1

Mg- 1

Al-1

Si-Network lattice

P4– 4

S8– 8

Cl2– 2

Ar-1

K- 1

Ca- 1
