The quantum numbers of an electron are n (determined by electron's energy), l (angular momentum), `m_l` (one component of angular momentum) and `m_s` (spin, or intrinsic magnetic moment), and they have to obey certain restrictions, which are:
`0 <=l<=n-1` (l is an integer)
`-l<=m_l<=l` (`m_l` is an integer)
`m_s` is a positive or negative half-integer.
So for n = 1, the only...
