Question

Calculate atomicity of : C2H6, ZnO, P4, S8

Answer 1

Hello there!

Atomicity means number of atoms in a molecules

C2H6 has 2 atoms of carbon and 6 aton of H so its atomicity is 8

ZnO has one atom of Zn and 1 atom of O so its atomicity is 2

P4 has 4 atoms its atomicity is 4

S8 has 8

Answer 2

atomicity = no. of atoms in one molecule

in c2h6,

2 C atoms and 6 H atoms

2+6=8

in zno,
1 zn atom and 1 o atom
1+1=2

in p4,
4 p atoms,
=4
in s8,
8 s atoms
=8
