What is the atomicity of Phosphorous?

Correct option is A

The correct answer is (a) Tetra-atomic
· The term atomicity refers to the number of atoms present in a molecule of an element. For phosphorus, its most stable and common form is P₄, which means it consists of four atoms in one molecule. This structure is known as tetra-atomic.
· However, phosphorus can exist in various forms, including white, red, and black phosphorus. Due to these different forms, phosphorus is generally referred to as a poly-atomic element because it can form molecules with multiple atoms (more than two).
· The atomicity of phosphorus, being more than one and varying in structure, qualifies it as poly-atomic, encompassing the different allotropic forms phosphorus can take .
