Match List I with List II and select the answer using the code...
Match List I with List II and select the answer using the code given below the Lists:
| List I (Element) | List II (Atomicity) |
|---|---|
| A. Phosphorus | 1. 2 |
| B. Nitrogen | 2. 1 |
| C. Neon | 3. 8 |
| D. Sulphur | 4. 4 |
Options
- AA-4, B-1, C-2, D-3
- BA-4, B-2, C-1, D-3
- CA-3, B-2, C-1, D-4
- DA-3, B-1, C-2, D-4
Correct answer
A. A-4, B-1, C-2, D-3
Step-by-step solution
Atomicity is the number of atoms present in one molecule of an element.
Phosphorus exists as molecules. Its atomicity is 4. Thus, A matches with 4.
Nitrogen exists as molecules. Its atomicity is 2. Thus, B matches with 1.
Neon is a noble gas and exists as monatomic . Its atomicity is 1. Thus, C matches with 2.
Sulphur exists as molecules. Its atomicity is 8. Thus, D matches with 3.
The correct matching is A-4, B-1, C-2, D-3.
Phosphorus exists as molecules. Its atomicity is 4. Thus, A matches with 4.
Nitrogen exists as molecules. Its atomicity is 2. Thus, B matches with 1.
