Multiple choice

In the hydrogen atom, the shape of an orbital and its number of angular nodes are set by the azimuthal quantum number ell. How many angular nodes does a p orbital (ell = 1) have?

3 angular nodes
1 angular node (one nodal plane through the nucleus)
0 angular nodes (spherically symmetric)
2 angular nodes (two nodal planes)
