Candidates were asked to write the full electronic configuration of the Fe2+cap F e raised to the 2 plus power Fe3+cap F e raised to the 3 plus power Solution: . Therefore, Fe2+cap F e raised to the 2 plus power Fe3+cap F e raised to the 3 plus power . Remember that electrons are lost from the subshell first. Insight: Fe3+cap F e raised to the 3 plus power is particularly stable because it possesses a half-filled
