Quizplus · Accepted Answer

The ground state of hydrogen has the quantum numbers $n = 1$ (principal quantum number), $l = 0$ (azimuthal or angular momentum quantum number), $m_l = 0$ (magnetic quantum number), and $m_s = \pm 1/2$ (spin quantum number), which corresponds to choice D.

In Its Ground State, the Quantum Numbers (n,l,m1,mS)\left( n , l , m _ { 1 } , m _ { S } \right)(n,l,m1​,mS​)
