What is the number of unpaired electrons in the $NO$ molecule?

What is the bond order of the $O_2$ molecule?

$A$ homonuclear diatomic gas molecule shows $2$-electron magnetic moment. The one-electron and two-electron reduced species obtained from the above gas molecule can act as both oxidizing and reducing agents. When the gas molecule is one-electron oxidized, the bond length decreases compared to the neutral molecule. The gas molecule is
