Question

Define the term atomicity.

Answer 1

• The number of atoms that constitute one molecule of an element, is called its atomicity.
• Depending upon the number of atoms in one molecule of an element, they are classified as monoatomic, diatomic, triatomic, and polyatomic molecules.
• For example, nitrogen$\left({\mathrm{N}}_2\right)$ and oxygen$\left({\mathrm{O}}_2\right)$ are diatomic in nature because each molecule of nitrogen and oxygen is two atoms of Nitrogen and oxygen respectively.
