There are three orbitals in a p subshell.
A p subshell contains three separate orbitals that each hold up to two electrons, so the whole p subshell can hold up to six electrons. Think of each orbital like a little cloud-shaped room where electrons live; the p orbitals are shaped like dumbbells and point in three different directions in space, which we call the x, y, and z directions, though you can just think of them as left-right, front-back, and up-down. Each orbital is at the same energy level, so electrons fill them following a rule that spreads electrons into separate orbitals first before pairing them. Because there are three of these rooms, atoms use p orbitals to make bonds and explain shapes of molecules in chemistry.
A common mistake is saying a p subshell has only one orbital because people picture just one dumbbell shape, and the quick fix is to remember there are three identical shapes pointing in three directions. Another error is thinking each orbital always has two electrons, when really electrons prefer to occupy empty orbitals singly first; reminding yourself of the rule that electrons fill empty orbitals before pairing keeps assignments correct. Some learners confuse the x y z labels with different energies, so it helps to recall that all three p orbitals in the same subshell have the same energy.
