What is the designation of fifth sub-shell?

The designation of the fifth sub-shell is 5s, 5p, 5d, and 5f, corresponding to the different types of orbitals that can exist in that energy level. Each type of orbital has a specific shape and can hold a certain number of electrons: s (2 electrons), p (6 electrons), d (10 electrons), and f (14 electrons). Thus, the fifth energy level can accommodate a maximum of 50 electrons when considering all of its sub-shells.
