I hate that I always have to waste my limited quanitty of questions for follow ups for a decent explaination.I don't understand.It must be in a +3 state?Why?F has a -1 charge, that means it would have:9p 10e due to it's 18.99 mass.and since the charge is -1, that would imply 10e.That means I need an element with +1 charge to balance, but also should have 12e.Mn has a charge of +2 generally, but it can have +3.I was given zero understanding of how it could be any element with a +1 charge that has those numbers of electrons.I need help understanding this.
