JEE Main2026Jan 21, Shift 1Chemistry

Which of the following represents the correct trend for the mentioned property?

A. $F > P > S > B$ — First Ionization Energy

B. $C l > F > S > P$ — Electron Affinity

C. $K > A l > M g > B$ — Metallic character

D. $K_{2} O > N a_{2} O > M g O > A l_{2} O_{3}$ — Basic character

Choose the correct answer from the option given below.

Solution

IE across period 2 (left to right): increases. $F > P > S > B$ — correct.

EA: $C l > F > S > P$ — correct (Cl > F due to small size of F).

Metallic character: $K > M g > A l > B$ (so option C is wrong).

Basic character of oxides: $K_{2} O > N a_{2} O > M g O > A l_{2} O_{3}$ — correct.

A, B and D are correct.
