The graph between  and  (radial distance) is shown below. This represents:

Canvas Classes · Accepted Answer

The graph shows  vs  with:
- A maximum at  (nucleus)
- Decreases to zero at one point (one radial node)
- Shows a second smaller maximum
- Then decreases to zero

This pattern (1 radial node, starts at maximum at nucleus) is characteristic of the 2s orbital:
- 2s: , , radial nodes =  ✓
- 1s has no nodes; 3s has 2 nodes; 2p has no radial nodes

Answer: Option (3) — 2s orbital
