Assign true $(T)$ or false $(F)$ for the following statements and select the correct option for your answer:
$(I)$ $I.P.$ of $O_{(g)}$ is less than $I.P.$ of $O^{-}_{(g)}$
$(II)$ $I.P.$ of $Ne_{(g)}$ is greater than $I.P.$ of $Ne^{+}_{(g)}$
$(III)$ $E.A.$ of $O^{+}_{(g)}$ is greater than $E.A.$ of $O_{(g)}$
$(IV)$ $I.P.$ of $N_{(g)}$ is greater than $I.P.$ of $N^{+}_{(g)}$
