PROBLEM 90P

What is the maximum number of electrons that can occupy the n = 4 quantum shell?

Solution 90P

Step 1:

The fourth shell has 4 subshells(s, p, d, f). The s subshell, which has 1 orbital with 2 electrons, the p subshell, which has 3 orbitals with 6 electrons, and the d subshell, which has 5 orbitals with 10 electrons, f subshell has 7 orbital , which has 14 electrons. For a total of 16 orbitals and 32 electrons.
