Which one of the following species is diamagnetic in nature?

Accepted Answer

TIPS/Formulae :

A diamagnetic substance contains no unpaired electron.

H_{2}

is diamagnetic as it contains all paired electrons

\underset{(d i a m a g n e t i c)}{H_{2} = σ_{b}^{2}}, \underset{(p a r a m a g n e t i c)}{H_{2}^{+} = σ_{b}^{1},} \underset{(p a r a m a g n e t i c)}{H_{2}^{-} = σ_{b}^{2},}

\underset{(p a r a m a g n e t i c)}{σ_{a}^{* 1}; H e_{2}^{+}} = \underset{(p a r a m a g n e t i c)}{σ_{b}^{2}, σ_{a}^{\neq 1}}
