Examiners report

Question 6 was poorly answered as it asked for the number of electrons in a p orbital. Very few students gave the correct answer of 2. The majority chose answer C (6) for the maximum number of electrons that can occupy a p-orbital, rather than A (2). It appears candidates reflexively conflated p-orbitals with the entire p subshell in any given period.
