Which of the following quantum number combinations is not allowed in a ground-state atom? (2, 1, 1, -½) (8, 7, -7, +½) (5, 5, -5, +½) (1, 0, 0, +½)

OpenStudy (madmerc):

I'm pretty sure it isn't the first one but I honestly don't know

Rules Governing the Allowed Combinations of Quantum Numbers * The three quantum numbers (n, l, and m) that describe an orbital are integers: 0, 1, 2, 3, and so on. * The principal quantum number (n) cannot be zero. The allowed values of n are therefore 1, 2, 3, 4, and so on. * The angular quantum number (l) can be any integer between 0 and n - 1. If n = 3, for example, l can be either 0, 1, or 2. * The magnetic quantum number (m) can be any integer between -l and +l. If l = 2, m can be either -2, -1, 0, +1, or +2. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch6/quantum.html#rules

@Cuanchi so it would be (1, 0, 0, +½) because of the zeros?

OpenStudy (madmerc):

It's (5, 5, -5, +½) I just took the test and got it right
