Question

Valency and atomicity of calcium, hydrogen, nitrogen, oxygen, chlorine, carbon, phosphorus and sulphur​

Answer 1

Answer:

what can I do for all items

tell please

Answer 2

Calcium - valency=K shell-2,L shell-8,M shell-8,N shell-2

atomicity=20

Hydrogen=Valency = K shell-1

Atomicity =1

Nitrogen - Valency =K shell-2,L shell-5

Atomicity =7

Oxygen =Valency = K shell-2,L shell-6

atomicity= 8

Chlorine =Valency =K shell-2,L shell-8,M shell-7

Atomicity =17

Carbon =Valency =K shell-2,L shell-4

Atomicity =6

Phorsphorus=Valency = K shell-2,L shell-8,M shell-5

Atomicity =15

Sulphur =Valency =K shell-2,L shell-8,M shell-6

Atomicity =16

Hope it would help you!
