MCQ
Which of the following can form a super oxide very easily?
- ASodium
- BPotassium
- ✓Caesium
- DLithium
✓
Answer
Correct option: C.
Caesium
The size of the atoms increases as we move down the group from lithium to caesium. Caesium cation has a large ionic size.
Similarly, the superoxide ion has a large ionic size. These ions form a stable lattice by efficient packing of ions.
Hence, caesium can form superoxide very easily.
