show charges on each atom in following bonds:
Cl-Cl is a covalent bond. No charge.
SrO is an ionic compound with Sr+2 and O -2.
HO is a polyatomic ion with a charge of OH^-.
Br-I is a covalent bond. no charge.
The Br-I is a polar covalent bond with the Br being slightly negative and the I slightly positive.
The OH^- is a polar covalent bond, also.
If you want the FORMAL charges, none of these answers are correct. you didn't specify exactly what you wanted.
What would the formal charges be?
Do you know how to do formal charges? If so, check me out on these. I'm not going to draw a diagram, and frankly, that's about the only way I can bre SURE I get them right.
Cl-Cl is zero f.c. on each Cl.
SrO. Sr has f.c. of +2 and O of -2.
OH^-. O has f.c. of -1, H is 0.
Br-I. Both have f.c. of 0.
