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).

Step-by-step solution

Bond order of the covalent molecule, AX is given as 2 . 5 , As AX is a covalent diatomic molecule of second row elements of periodic table we can consider CO ,   NO but bond order of CO having 14 electrons which is isoelectronic to nitrogen should be equal to 3 and NO having 15 electrons will have a bond order of 2 . 5 . Molecular orbital configuration and bond order calculation of NO is ABMO = antibonding molecular orbital Bond order = Number of bonding electrons - number of anti bonding electrons. Note: Tota
