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
