p orbitals have angular momentum around an axis. There are three p orbitals per energy level. They can be visualized as balloon-shaped dumbells of probability density tied together by their mouths.

This is the second type of electron orbital. There are three p orbitals per shell starting with the second electron shell. Each p orbital is a pair of lobes along one of the three axes (x, y, and z). The p stands for principal.

These orbitals are particularly associated with the chemistry of the main group elements.

The following is a Px orbital. Rotate this picture onto the y-axis and you get Py. Rotate it onto the z-axis (not shown, coming in and out of your screen) and you get Pz
