Vedclass · Answer

(A) $(I)$ $I.P.$ of $O_{(g)}$ is less than $I.P.$ of $O^{-}_{(g)}$ is $False$ because removing an electron from a negatively charged ion is easier than from a neutral atom due to electron-electron repulsion.$(II)$ $I.P.$ of $Ne_{(g)}$ is less than $I.P.$ of $Ne^{+}_{(g)}$ because removing an electron from a cation requires more energy than from a neutral atom. Thus,the statement is $False$.$(III)$ $E.A.$ of $O^{+}_{(g)}$ is greater than $E.A.$ of $O_{(g)}$ is $True$ because $O^{+}$ has a higher effective nuclear charge and is more electron-attracting than neutral $O$.$(IV)$ $I.P.$ of $N_{(g)}$ is less than $I.P.$ of $N^{+}_{(g)}$ because removing an electron from a cation is harder. Thus,the statement is $False$.Therefore,the sequence is $F, F, T, F$.
