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

To determine the maximum number of electrons that can occupy a 4p sub-shell, we must consider the general rule for electron configuration.

A p sub-shell can hold a maximum of 6 electrons. This is derived from the fact that a p sub-shell consists of three orbitals (each can hold 2 electrons), thus:

$ext{Number of electrons} = ext{Number of orbitals} imes 2 = 3 imes 2 = 6$

Therefore, the correct answer is B: 6.
