The set of principal (n), .azimuthal (l) and magnetic `(m_(1))` quantum number that is not allowed for the electron in H-atom isA. n = 3, l = 1, `m_(1) = -1`B. n = 3, l = 0, `m_(1) = 0`C. n = 2, l = 1, `m_(1)= 0`D. n = 2, l = 2, `m_(1) = -1` |

Answer» Correct Answer - D n is always greater than l and m = - l……….0 ………..+l If n = 2, then l = 0, 1 and `m_(l) = 0, { -1, 0, + 1}` |
