Q88 · Chemistry
Consider the following schematic plots of orbital wavefunction () against distance (r) from the nucleus.
[Figure: four plots A, B, C, D of vs r]
The figure representing two radial nodes in the orbital is
The figure, described in words
Four plots of psi_r vs r: A positive and decaying (no node); B starts high, dips below zero once and returns towards zero; C starts high, crosses below zero, rises to a positive hump, then levels off; D starts at zero, positive hump, dips below zero, then levels off.
