Chemistry-Atomic Radius
NEET Chemistry Atomic Radius Match the Following Question
Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Atomic Radius of Cl (i) 198 pm (b) Ionic Radius of F– (ii) 136 pm (c) Cation Size (iii) Smaller than parent atom (d) Anion Size (iv) Larger than parent atom
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The atomic radius of chlorine is calculated from the bond distance in Cl2, which is 198 pm. The ionic radius of F– is 136 pm, and it is established that cations are smaller than their parent atoms, while anions are larger due to increased electron repulsion.
