$H^{-} > H > H^{+}$

Vedclass · Answer

(A) The size of an anion is always larger than its parent atom due to an increase in electron-electron repulsion and a decrease in effective nuclear charge $(Z_{eff})$. Conversely,the size of a cation is always smaller than its parent atom due to the loss of an electron shell and an increase in effective nuclear charge $(Z_{eff})$. For the hydrogen species: $H^{-}$ has two electrons,$H$ has one electron,and $H^{+}$ has no electrons. Therefore,the correct order of radius is $H^{-} > H > H^{+}$.
