Q. 64.2( 5 Votes )

Write the atomicity of the following:

(i) I2 (ii) H2S

(iii) HNO3 (iv) Na2SO4

(v) S8

Answer :

Atomicity: The number of atoms constituting a molecule is known as its atomicity.

i. In I2, there are two atoms of iodine constituting a molecule.

Hence, the atomicity is 2 (diatomic).

ii. In H2S, there are two atoms of hydrogen and one atom of Sulphur constituting a molecule of H2S. Hence, the atomicity is 3 (triatomic).

iii. In HNO3, there are three atoms of oxygen, one atom of nitrogen and one atom of hydrogen sulphur constituting a molecule of HNO3. Hence, the atomicity is five.

iv. In Na2SO4, there are two atoms of sodium, one atom of Sulphur and four atoms of oxygen constituting a molecule of Na2SO4 Hence, the atomicity is seven.

v. In S8, there are eight atoms of sulphur constituting a molecule.

Hence, the atomicity is eight.
