Which of the following order of radius is/are CORRECT :-
Options:(select one or more)
Answer:
A, D
Solution:
Across a period → radius decreases, Down a group → radius increases
S²⁻ < Br⁻ (S²⁻ smaller than Br⁻ because S²⁻ is in higher period?) Actually S²⁻ < Br⁻ is correct considering period vs group trend
P³⁻ < Se²⁻ (P³⁻ is larger)
N³⁻ > I⁻ (N³⁻ smaller than I⁻)
Cl⁻ > O²⁻ (Cl⁻ is larger than O²⁻)
Answer: A, D
