A. an electron in a 4p state is always farther from the center of the atom than is an electron in a 2p state.
B. an electron in a 2p state can be found at the atom’s center.
C. a 3p state has 3 units of orbital angular momentum.
D. none of the above is true.
This illustration shows radial probability distribution functions for three hydrogen-atom wave functions, plotted versus r/a (r = distance from the center of the atom and a = 0.0529 nm). It follows that
