How many and which quantum numbers are required to completely define :
(i) an orbital and

How many quantum numbers are required to define the electron in atom?

Which set of quantum numbers could repesent an electron in a 5f orbital ?

Quantum number of an atom can be defined on the basis of

An electron in an atom can be completely designated with the help of four quantum numbers. Out of these, the first three i.e., principal (n), azimuthal (l) and magnetic (m) quantum number are obtained from the solution of Shrodinger wave equation while the spin(s) quantum number arises from the spin of the electron around its axis clockwise or anticlockwise. Of these principal quantum number tells about the size, azimuthal quantum number about the shape and magnetic quantum signifies the orientation of the electron orbital. How many electrons in a given atom have the following set of quantum numbers? n = 3, l =2, m = +2, s = -1//2
