Question

Atomicity of phosphorous is?

Answer 1

Atomicity:

1. Atomicity refers to the total number of atoms in a molecule.
2. Phosphorus is a chemical element with the atomic number 15 and is represented by letter $\mathrm{P}$.
3. White phosphorus and red phosphorus are the two major forms of phosphorus, however, because of their strong reactivity, neither one is ever found on earth as a free product.
4. It exists in ${\mathrm{P}}_4$ form i.e. the number of atoms in a phosphorus molecule is $4$, hence the atomicity of phosphorous is $4$.

Therefore, the atomicity of Phosphorous is $4$
