Question

Consider ground-state helium having two electrons in orbit. If one of the electrons has quantum numbers (n, ll, m1, ms) of 1, 0, 0, -1/2 respectively, the quantum numbers for the other electron will be

Answer 1

The quantum numbers for the second electron in ground-state helium will be the same as the first electron, except for the spin quantum number.

Step-by-step explanation:

The quantum numbers for the other electron in ground-state helium will be the same as the first electron, except for the spin quantum number (ms), which will have the opposite sign. The first electron has quantum numbers (n=1, l=0, m1=0, ms=-1/2), so the second electron will have the same values for n, l, and m1, but the ms will be +1/2.
