What 4 quantum numbers describes one of the outermost electrons in a strontium atom in ground state?

5,0,0,1/2

Is my answer correct?

Yes. This is 1 electron in the 5s2.
n= 5
l= 0
m_l = 0
m_s = one electron is +1/2 and the other electron is -1/2. Technically, these are not exactly +1/2 and -1/2 but the +/- 1/2 are in units of h/2*pi. But I'm getting ahead of myself.
