Question
The task presented is to rank ions in each set according to their size, from largest to smallest.

### (a) Ranking the ions: 
Options are given to rank the ions based on size:

- \( \text{Se}^{2-} \) 
- \( \text{Rb}^{+} \)
- \( \text{Br}^{-} \)

The choices for ranking are:

- \( \text{Se}^{2-} > \text{Rb}^{+} > \text{Br}^{-} \)
- \( \text{Rb}^{+} > \text{Se}^{2-} > \text{Br}^{-} \)
- \( \text{Br}^{-} > \text{Se}^{2-} > \text{Rb}^{+} \)

---

### (b) Ranking the ions:
Options for ranking these ions:

- \( \text{Li}^{+} \)
- \( \text{K}^{+} \)
- \( \text{Na}^{+} \)

The available rankings are:

- \( \text{Li}^{+} > \text{K}^{+} > \text{Na}^{+} \)
- \( \text{K}^{+} > \text{Na}^{+} > \text{Li}^{+} \)
- \( \text{Na}^{+} > \text{Li}^{+} > \text{K}^{+} \)

---

### (c) Ranking the ions:
Options for arranging these ions by size:

- \( \text{Sr}^{2+} \)
- \( \text{Ba}^{2+} \)
- \( \text{Cs}^{+} \)

The possible rankings are:

- \( \text{Sr}^{2+} > \text{Ba}^{2+} > \text{Cs}^{+} \)
- \( \text{Ba}^{2+} > \text{Sr}^{2+} > \text{Cs}^{+} \)
- \( \text{Cs}^{+} > \text{Ba}^{2+} > \text{Sr}^{2+} \)
