The total number of molecular orbitals formed from 2s and 2p atomic orbitals of a diatomic molecule is _________.
The total number of molecular orbitals formed from 2s and 2p atomic orbitals of a diatomic molecule is _________.
Solution and Explanation
The molecular orbitals formed from 2s and 2p atomic orbitals are as follows:
\(• Two\ molecular\ orbitals\ of\ 2s\ and\ σ ∗2s\)
\(• Six\ molecular\ orbitals\ of\ 2p: σ2pz, σ ∗2pz, π2px, π2py, π ∗2px, π ∗2py.\)
Thus, the total number of molecular orbitals formed is 8.

Molecular Orbital Theory
The Molecular Orbital Theory is a more sophisticated model of chemical bonding where new molecular orbitals are generated using a mathematical process called Linear Combination of Atomic Orbitals (LCAO).
Molecular Orbital theory is a chemical bonding theory that states that individual atoms combine together to form molecular orbitals. Due to this arrangement in MOT Theory, electrons associated with different nuclei can be found in different atomic orbitals. In molecular orbital theory, the electrons present in a molecule are not assigned to individual chemical bonds between the atoms. Rather, they are treated as moving under the influence of the atomic nuclei in the entire molecule.
