Chemistry-Atomic Radius
NEET Chemistry Atomic Radius Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
Column-I Column-II (a) Cation Radius (i) Larger than parent atom (b) Anion Radius (ii) Smaller than parent atom (c) Neutral Atom (iii) Equal to parent atom (d) Ionic Radius (iv) Estimated from ionic crystals
Choose the correct matching:
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-iv, b-iii, c-ii, d-i
D
a-iii, b-iv, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
Cations have a smaller radius than their parent atoms due to fewer electrons, while anions are larger due to added electrons causing increased repulsion. Ionic radius can be estimated from the distances between cations and anions in ionic crystals.
