Question

a) Draw all the possible Lewis structures for the following ions:

(PO4)^3-

(SO3)^2-

b) Assign formal charges to each atom in each resonance structure

c) indicate the most plausible Lewis structure.

d) Indicate the approximate bond angles for each ion.

(e) determine the names for the molecular geometry. 

Answer 1

There is a LOT of stuff to unpack in this question including concepts that you mentioned being:

Lewis structures

Formal charges

Resonance structures

Molecular geometry

Each could require a lot more help than what is provided in the video. Please reach out if you wish to get more help.
