a) Element P forms an ion P²⁻ with electron arrangement 2.8.8. This means the neutral atom P has 18 - 2 = 16 electrons. The electron arrangement of neutral P is 2.8.6. Step 1: Determine the period. The number of electron shells is 3. Period: 3 Step 2: Determine the group. The number of valence electrons is 6. Group: 16 (or VI) b) Element N has an ion N' with electron arrangement 2.8. This implies N' is N³⁻, so neutral N has 7 electrons with electron arrangement 2.5 (5 valence electrons). Element O has an ion
