The term atomic orbital refers to the physical region or space where the electron can be calculated to be present

Each orbital in an atom is characterized by a unique set of values of the three quantum numbers:

Each such orbital can be occupied by a maximum of two electrons, each with its own spin quantum number s.

The simple names s orbitalp orbitald orbital and f orbital refer to orbitals with angular momentum quantum number  = 0, 1, 2 and 3 respectively
