Answer:check attached diagram
Explanation:
In order to draw a lewis structure for any ion,molecules or compounds, the following step must be followed;
FIRST STEP: select a central atom, the central atom should be the most electronegative as compare to other atoms in the ion, molecule or compounds.
For (a),(b), (c) and (d); Iodine,Phosphorus, Chlorine and Arsenic respectively.
SECOND STEP: Join this central atom to other atoms with a single bond
THIRD STEP: calculate the number of π electron using the formula below;
P= 6n +2 - V. Where V= valence electron, p= number of pie electron, n= number of atom
V can be calculated;
V= (6+6+6+6+5+1) - (-2)
=32
FOUTH STEP: complete the structure drawing it resonance
