Chemistry-Atomic Radius
NEET Chemistry Atomic Radius Match the Following Question
Type: Match the Following-match the column-Easy-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Ionic radius of F– (i) 136 pm (b) Cation smaller than parent atom (ii) Increased electron repulsion (c) Atomic radius of Cl (iii) Covalent bond distance (d) Anion larger than parent atom (iv) Fewer electrons
Choose the correct matching:
A
a-i, b-iv, c-iii, d-ii
B
a-ii, b-iv, c-i, d-iii
C
a-iii, b-ii, c-i, d-iv
D
a-i, b-ii, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
The ionic radius of F– is 136 pm, a cation is smaller than its parent atom due to having fewer electrons, the atomic radius of Cl can be derived from the bond distance, and an anion is larger than its parent atom because of increased electron repulsion.
