Question

how many electrons in an atom may have the following Quantum numbers:-
1) n=4,s= -1/2
2)n=3, l=0

Answer 1

Thus, the fourth level can hold up to 32 electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals. The sublevels of the first four principal energy levels and the maximum number of electrons that the sublevels can contain are summarized in Table 5.1.
