Question

Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, l, m l , and ms)A. 0, 5, 4, 0B. 6, 3, 0, 1/2C. 6, 6, 7, 6

Answer 1

answer and explanation

allowed quantum numbers are governed by a set of rules and one of the rules is that the principal quantum number (n) cannot be zero. therefore, A is not acceptable. another rule is that l must always be n-1 and so C is not allowed as we cannot have 7 in the quantum number set.

therefore the acceptable set is B
