Among the species given below, the total number of diamagnetic species is______

H atom, $N O_{2}$ -monomer, $O_{2}^{-}$ (superoxide), dimeric sulphur in vapour phase,
$M n_{3} O_{4}, (N H_{4})_{2} [F e C l_{4}], (N H_{4})_{2} [N i C l_{4}], K_{2} M n O_{4}, K_{2} C r O_{4}$

Solution

Paramagnetic

odd electron species Paramagnetic

$O_{2}^{-}$ (superoxide) = One unpaired electrons in $π *$ molecular orbital Paramagnetic

$S_{2}$ (in vapour phase) = same as $O_{2},$ two unpaired $e^{-} s$ are present in Molecular orbital. Paramagnetic

Thus, $K M n O_{4}$ is also paramagnetic.
