Question

PLEASE HELP!!! LOTS OF POINTS!!!

Number of valence electrons:

Barium: 2
Phosphorus: 5
Oxygen: 6

b) Based on the number of valence electrons, write the monatomic ion (symbol with charge) each element may form.

c) Phosphorus and oxygen can bond to form a polyatomic ion. Write the formula of for this ion and be sure to include the ion charge.

d) Using the monatomic ions you listed above in (b), the polyatomic ion from (c), write the formulas for the three ionic compounds these ions could form.

Answer 1

Answer: oxygen needs two take away- two rings

phosphorus needs three taken away- three rings

barium needs two added- six rings

oxygen and barium are the same.
