Question

Which of the following is the correct plot for the probability density  as a function of distance '' of the electron from the nucleus for 2s orbital?

Canvas Classes · Accepted Answer

For 2s orbital,  characteristics:
- Maximum at  (nucleus)
- Decreases, reaches zero at one radial node ()
- Increases again to a second maximum
- Then decreases to zero as

The correct plot shows  starting high at the nucleus, dropping to zero (node), then showing a second smaller peak, then going to zero.
