Question

Define atomicity . What is the atomicity of phosphorus? Write it's chemical formula .

Answer 1

Answer:

Diphosphorus is obtained by heating white phosphorus of tetraphosphorus P4 (atomicity of phosphorus in this is 4) at 1100K. P4. Note: There are chances that atomicity is confused with valency. Atomicity gives the number of atoms present in a molecule.

Answer 2

Atomicity is defined as the total number of atoms that constitute a molecule. For example, each molecule of oxygen is composed of two oxygen atoms. So atomicity of oxygen is 2.In older contexts, the term atomicity is sometimes used in the same sense as valency.

Atomicity is the number of atoms of an element present in one molecule of that element. The number of atoms present in a molecule of phosphorus are 4. So the atomicity of phosphorus is 4.

Formula -

Atomicity = Molecular mass/Atomic mass
