[If it's possible, I need an answer by tomorrow. I'm cursing myself for not bringing home my chemistry book, hehe]

An oxygen ion has a -2 charge -
a. How many protons does the oxygen ion have?
b. How many electrons does the oxygen ion have?

[Oh and it's not needed but if you could explain why that'd help me out for future questions, I swear I don't remember learning how to figure this out!]
