• What is atomicity ?

$\huge{\textbf{\textsf{{\orange{A}}{\blue{n}}{\pink{s}}{\purple{w}}{\red{e}}{\green{r}}}}}$

• Atomicity is defined as the total number of atoms present in a molecule. It cannot be broken down into further small portions.

• ★ Atomicity of a molecule is also determined as the ratio of molecular mass to atomic mass.

• For example, in oxygen molecule, the molecular mass is 32 (= 2×16 ) and the atomic mass is 16. So, to derive the value of atomicity, we divide 32 / 16 = 2. Thus, the atomicity of oxygen, O2, is 2.
