The maximum number of electrons that can occupy a 4p sub-shell is A - VCE - SSCE Chemistry - Question 2 - 2002 - Paper 1

The 4p sub-shell belongs to the p sub-level, which can hold a maximum of 6 electrons. This is because each p subshell has three orbitals, and each orbital can hold 2 electrons according to the Pauli exclusion principle. Therefore, the maximum number of electrons in a 4p sub-shell is:

$6 = 3 ext{ (orbitals)} imes 2 ext{ (electrons per orbital)}$
