Solve the following

Question:

$A \mathrm{X}$ is a covalent diatomic molecule where $\mathrm{A}$ and $X$ are second row elements of periodic table. Based on Molecular orbital theory, the bond order of $\mathrm{AX}$ is 25 . The total number of electrons in $\mathrm{AX}$ is (Round off to the Nearest Integer).

Solution:

(15)

AX is a covalent diatomic molecule. The molecule is NO. Total no. of electrons is 15 .
