Which statement is/are correct
(a) Formation of anions with unit charge (e.g`CI^(Θ) Br^(Θ),Br^(Θ),I^(Θ)` are very common because the `EA` of these atoms is positive and quite high or `Delta_(eg)H^(Θ)` of these atoms are negative and quite high
(b) `EA'` or `Delta_(eg)H^(Θ)` of these atoms is positive and quite high
(c ) Formation of anions with -23 charge `(e.g.S^(2-),O^(2))` is not so easy as their second `EA"` are negative i.e energy is needed to add second electron
(d) Formation of anions with `-3` charge `(e.g. N^(3-),p^(3-))` is almost rare as the third `Delta_(eg)H^(Θ)` are positive i,e energy in needed to add third electron .

Answer

a,c,d

Explanation

Note By convention `EA` is assigned as+vebut `Delta_(eg)H^(Θ)` is assigned as -ve value for exothermic processes energy is released and vice versa So statement a,c and d are correct .
