In sub-shell 5, there are a total of five orbitals: three p orbitals and two s orbitals. The p orbitals are labeled as px, py, and pz, while the s orbitals are labeled as 5s and 5s*. Each of these orbitals can accommodate a maximum of two electrons, so the p subshell can hold a maximum of six electrons, and the s subshell can hold a maximum of two electrons. Therefore, the total capacity of sub-shell 5 is eight electrons.
