Question

10. The increasing order of the atomic radii of the following elements is
(A) C
(B)O
(C) F
(D) CI
(E) Br
(a) (A) < (B) < (C) < (D) < E)
b) (c) < (B) < (A) < (D) <
c) (D) < (C) < (B) < (A < (E)
(0) (B) < (C) < (D) < (A < (E​

Answer 1

Answer:

A is the answer

Explanation:

This is because when we move left to right in a periodic table we see trend of radii changes so we take electronegativity and Valence shell distance or screening effect in consideration . According to that carbon is most electronegative then O then F , and for Cl and Br screening effect concept will apply.

Answer 2

Option b) (c) < (B) < (A) < (D) < (E)
