In IB chemistry:

• The S sub levels contain just one orbital
• The 2p sub level however  is made up of three 2p orbitals (px py pz)

Cross section of the electron density of the 1s and 2s orbitals together. (2s is bigger)

The 2p orbitals point at 90 ^o from each other and all have the same energy (degenerate)

This diagram shows the orbitals which make up the 2s and 2p sub shells; the 2nd main energy level in IB chemistry
