NEET Chemistry Atomic Radius Match the Following Question
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) Atomic radius of Chlorine (Cl) | (iii) Covalent radius calculation |
| (d) Ionic radius of Fluoride (F–) | (iv) Estimation based on ionic crystal distances |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-iv, b-iii, c-ii, d-i
a-ii, b-iv, c-i, d-iii
Correct Answer
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-electron repulsion. The atomic radius of chlorine can be estimated from bond distances, and the ionic radius of fluoride can be measured through distances in ionic crystals.
