Question

Can you help me answer these 5 questions please

1. How many total valence electrons will there be on the PO₄^3- ion (a -3 ion)?

2. How many lone pairs of electrons are on the entire structure in the correct Lewis structure for CS₂ ?

3. How many lone pairs of electrons will be on the central atom in the correct Lewis structure for PBr₅?​​​​​​​

4. Which fo the following atoms can have an expanded octet?

A. S

B. O

C. Ne

D. H

E. F

5. Which of the following statements best describes how resonance forms relate to the actual structure of a molecule or ion?

A. When a molecule or ion has several relevant resonance structures the forms do not interconvert, but some fraction of all the molecule/ion will be in each resonance form.

B. The actual form of a molecule or ion will be a hybrid or averaging of the different relevant resonance forms.

C. Molecules and ions with resonance forms will rapidly interconvert between their relevant resonance structures.
