The electron are distributed around the nucleus in various energy levels shells, subshells and orbitals. A set of quantum numbers completely describe the position and total energy of electron in an atom. The various permitted values of quantum numbers are : principal, n = 1,2,3,4...... azimuthal , l = 0,1,2,....(n -1) magnetic, m_l = -l .....0 .....+ l spin, m_s = +1//2 and -1//2 . Is the following set of quantum numbers possible or not ? n = 3, l = 2, m = 0, s = -1//2 .
