Choose the INCORRECT comparison(s) regarding the indicated properties :

Answer:

A, B, C, D

Solution:

* (A) Incorrect: Electronegativity increases across a period, so the correct order is $F > O > N$ .

* (B) Incorrect: Atomic radius increases down a group, so the correct order is $I > B r > Cl$ .

* (C) Incorrect: Ionization energy decreases down a group, making the correct order $L i > N a > K$ .

* (D) Incorrect: Atomic radius increases down a group, meaning the correct order is $K > N a > L i$ .
