Aug 04, 2017 · What is a Lone Pair. Lone pair is a pair of electrons that are not in a bond. The electrons of the lone pair belong to the same atom. Therefore, a lone pair is also called a non-bonding electron pair.Although electrons in the innermost shells are also coupled and do not participate in the bonding, they are not considered as lone pairs.
In chemistry, a molecular orbital (MO) is a mathematical function describing the wave-like behavior of an electron in a molecule.This function can be used to calculate chemical and physical properties such as the probability of finding an electron in any specific region. The term orbital was introduced by Robert S. Mulliken in 1932 as an abbreviation for one-electron orbital wave function.

Valence Bond Model vs. Molecular Orbital Theory. Because arguments based on atomic orbitals focus on the bonds formed between valence electrons on an atom, they are often said to involve a valence-bond theory. The valence-bond model can’t adequately explain the fact that some molecules contains two equivalent bonds with a bond order between that of a single bond and a double bond.
