Options
- A. A-4, B-1, C-2, D-3
- B. A-4, B-2, C-1, D-3
- C. A-3, B-2, C-1, D-4
- D. A-3, B-1, C-2, D-4
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 P_4 molecules. Its atomicity is 4. Thus, A matches with 4. Nitrogen exists as N_2 molecules. Its atomicity is 2. Thus, B matches with 1. Neon is a noble gas and exists as monatomic Ne. Its atomicity is 1. Thus, C matches with 2. Sulphur exists as S_8 molecules. Its atomicity is 8. Thus, D matches with 3. The correct matching is A-4, B-1, C-2, D-3.
