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) Ionic Radius | (iii) Estimated from distances in ionic crystals |
| (d) Atomic Radius | (iv) Determined from bond distance in covalent molecules |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-ii, c-iii, d-i
a-ii, b-i, c-iv, 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 ionic radius is estimated from the distances in ionic crystals, while the atomic radius is calculated from bond distances in covalent molecules, such as chlorine.
