Question

What is atomicity give atomicity of H₂S and HNO3​

Answer 1

Explanation:

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

Answer 2

Answer:

of atoms are present in the molecule..... Now, ✨=> ( 1 ) I2 :- The Atomicity of I2 is 2 because it contains two atoms in its molecule...... ... ✨=> ( 3 ) HNO3 :- The Atomicity of HNO3 is 5 because it contains one atom of Hydrogen, one atom of Nitrogen and 3 atoms of Oxygen
