Unformatted text preview: 1 can only be 0. Combined with the two possible values of m s , this gives a total of 2 possible combinations of n, l, m1, and ms: • • For the 5s subshell, we have n = 5 and l = 0. When l = 0, m1 = 0. We have 2 combinations of ms: • All the quantum states in the 2p subshell have n = 2 and l = 1. When l = 1. The allowed values of m1 are 1, 0, and 1. ms is either 1/2 or 1/2. so we have 6 possible combinations: • You need one final piece of information to fill in the table: because of the Pauli principle, each electron in an atom must be in a different quantum state. Therefore, the maximum number of electrons that can be in a subshell is just equal to the number of states in the subshell. Here's the completed table:...
