In the second energy level, there are four orbitals - one 2s orbital and three 2p orbitals.
16 orbitals in the 4th energy level. One s orbital, three p orbitals, five d orbitals, seven f orbitals Elements where the 4th principal energy level are filled are:- period 4 4s and 4p (starting with potassium) period 5 4d starting with Yttrium Lanthanides 4f starting with cerium
There are two sublevels in the second principle energy level. The s sublevel has one orbital and the p sublevel has 3, for a total of 4 orbitals.
There are five d orbitals in one energy level. These orbitals are designated as dxy, dyz, dxz, dz2, and dx2-y2. Each d orbital can hold a maximum of 2 electrons.
There are a total of four orbitals that can exist at the second main energy level: one s orbital and three p orbitals. The second main energy level corresponds to the n=2 energy level in an atom according to the Aufbau principle.

P orbitals at the same energy level have the same energy but differ in their spatial orientation. There are three p orbitals at each energy level (labeled as px, py, pz) that are oriented along the x, y, and z-axes, respectively. These orbitals have the same energy, but they have different spatial shapes and orientations.
