The total number of molecular orbitals formed from $2 \mathrm{~s}$ and $2 \mathrm{p}$ atomic orbitals of a diatomic molecule
Use the molecular orbital energy level diagram to show that $\mathrm{N}_{2}$ would be expected to have a triple bond, $\mathrm{F}_{2}$ a single bond and $\mathrm{Ne}_{2}$ no bond.
$AX$ is a covalent diatomic molecule where $A$ and $X$ are second row elements of periodic table. Based on Molecular orbital theory, the bond order of $AX$ is $2.5$. The total number of electrons in $AX$ is ........... (Round off to the Nearest Integer).
