There are many more than four orbitals in an atom! The types of orbitals are defined by their shape, and there are four basic types of orbitals, with even more sub-levels within those.

Here's the breakdown:

* s orbitals: These are spherical in shape. There's only one s orbital in each energy level.

* p orbitals: These are dumbbell-shaped, with two lobes on either side of the nucleus. There are three p orbitals per energy level (px, py, and pz), oriented along the x, y, and z axes.

* d orbitals: These have more complex shapes, including a cloverleaf and a dumbbell with a donut around the center. There are five d orbitals in each energy level.

* f orbitals: These are even more complex, with even more lobes and nodes. There are seven f orbitals in each energy level.

Therefore, there are four basic types of orbitals (s, p, d, and f), but there are many more individual orbitals within each type.
