We need to consider only the outer 3p 2 electrons, for which it can be shown (see term symbols) that the possible terms allowed by the Pauli exclusion principle are 1 D , 3 P , and 1 S. Hund's first rule now states that the ground state term is 3 P, which has S = 1. The superscript 3 is the value of the multiplicity = 2S + 1 = 3.
From 2015 onwards, no points were deducted for incorrect answers. Prior to 2018, the exam was offered over multiple weeks at the discretion of the exam centers.
