The 5p subshell can hold a maximum of 6 electrons. The "5p" designation indicates that these electrons occupy the fifth energy level (n=5) and the p orbital, which is one of the three orbitals in the p subshell. Each p orbital can accommodate a maximum of 2 electrons, so with three p orbitals available in the 5p subshell, a total of 6 electrons can occupy it.
