Question

What is the atomicity of ${\mathrm{H}}_2{\mathrm{SO}}_4$?

Answer 1

Atomicity

• The number of atoms constituting a molecule is known as its atomicity.
• Atomicity is monoatomic if there is only one atom present, diatomic if there are two atoms present, triatomic if there are three atoms present, and so on.
• If there are more than four atoms present, the atomicity is polyatomic.

Atomicity of ${\mathrm{H}}_2{\mathrm{SO}}_4$

• ${\mathrm{H}}_2{\mathrm{SO}}_4$ is composed of two atoms of hydrogen, one atom of sulfur, and four atoms of oxygen.
• The total number of atoms in ${\mathrm{H}}_2{\mathrm{SO}}_4$ is $7$.
• So, ${\mathrm{H}}_2{\mathrm{SO}}_4$ is polyatomic.
