Orbitals have different shapes. The four types of orbitals from least to most energy are, s, p, d, and f.

**S orbital:** Spherical in shape; one s orbital per energy level; and has a maximum of 2 electrons.

**P orbital:** Dumbbell shape (fat figure 8); 3 possible p orbitals in energy level 2 and higher; and has a maximum of 2 electrons per orbital.  **d orbital:** Cloverleaf shape; 5 possible d-orbitals in energy level 3 and higher; and each d-orbit has a maximum of 2 electrons.  **f orbital:** A more complex shape;7 possible f-orbitals in energy level 4 and higher; and each f-orbit has a  maximum of 2 electrons.
