Question

$AX$ is a covalent diatomic molecule where $A$ and $X$ are second-row elements of the 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).

Answer 1

Answer: (15)

In molecular orbital diagram, for the bond order to $2.5$, they should have a total of $15$ electrons. Thus, the compound $AX$ is NO (covalent compound).
