Question

how is Phosphorus a Tetra atomic molecule why​

Answer 1

Answer:Nitrogen is smaller in size hence it forms multiple bonds with other nitrogen and exists as diatomic molecule. Whereas phosphorus atomic size is more so it can form single bond with other phosphorus atoms. Hence it exists as tetra atomic molecule.Hence; Phosphorus is tetratomic.

Answer 2

Phosphorus a Tetra atomic molecule

Explanation:

• Tetra atomic elements are those which are made up of four atoms.
• A common and biologically important element that consists as molecules of four atoms chemically bonded together is the element phosphorus.
• For example phosphorus $P_4$
• Phosphorus can form a $P_4$  white phosphorus tetrahedron because it can form three bonds, while sulfur can only form two bonds. Therefore sulfur forms rings and chains only. The most stable allotrope of phosphorus, red phosphorus, is a cross-linked, polymeric chain of atoms.
