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) Cation (i) Larger than parent atom (b) Anion (ii) Smaller than parent atom (c) Ionic Radius (iii) Distance in ionic crystals (d) Atomic Radius (iv) Distance in covalent molecules
Choose the correct matching:
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iv, c-iii, d-i
D
a-iii, b-ii, c-i, d-iv
Correct Answer
Option A
Detailed Explanation
Cations are smaller than their parent atoms due to the loss of electrons, while anions are larger due to the gain of electrons, leading to increased electron repulsion. The ionic radius is defined by the distance between cations and anions in ionic crystals, while the atomic radius can be estimated from covalent bonds.
