because it's an electron-pair acceptor

I also had a question for this hw problem. For b) BF3, why is it an acid, I thought it couldn't accept anymore electrons because b valence electrons is 3 and its already filled by 3 F's?

BF3 is an acid because the boron atom can still complete the octet by accepting another electron pair.

Yes, Ag+ + e- -> Ag, it can accept electron to be back to original state,. By definition, it is a Lewis acid.

Would F- be a base or an acid being that F alone doesn't fill the valence shell?
