Concept explainers
(a)
Interpretation:
The number of electron pairs of a phosphorus atom in
Concept Introduction:
Electron pairs comprise of double electrons with different spins present in the same molecular orbital. There are two types of electron pair, one is lone pair which refers to the pair of electrons that is not shared in the covalent bond and is sometimes called unshared pair of electrons and the other is bond pair which refers to the pair of electrons that are mutually shared with other atoms through a covalent bond.
Lone pair involves two electrons of similar atoms that occupy same molecular orbital and bond pair includes two electrons of different atom in different orbitals and forms pi or sigma bond.

Interpretation:
The number of electron pairs of iodine atom in
