According to molecular orbital theory,the total number of bonding electron pairs in $O_2$ is

Which of the following is incorrect regarding the conversion of $N_2$ and $O_2$ into their respective monocations $N_2^+$ and $O_2^+$?

The correct bond order in the following species is

The changes in bond length with respect to $N-N$ and $O-O$,when $N_2$ becomes $N_2^{+}$ and $O_2$ becomes $O_2^{+}$ are respectively

Provide the electron configuration,magnetic property,bond order,and molecular orbital energy diagram for the fluorine $(F_2)$ molecule.

Consider the following statements.
$I$. In the conversion of $O_2$ to $O_2^{2+}$,bond order decreases.
$II$. In the conversion of $O_2$ to $O_2^{2+}$,magnetic property is not changed.
$III$. In the conversion of $O_2$ to $O_2^{2+}$,bond length decreases.
$IV$. $O_2^{2-}$ and $B_2$ have same bond order.
Identify the correct statements.
