The last statement holds true, if u think of it in terms of cations and anions it should make more sense. Cations are positively charged (think: CAT’s have PAWS) and anions are negative, most would think that if the metal is positively charged then it gains electrons and the opposite for negative ones but this is false. You can think of it like this: cations give AWAY elections, which is a POSITIVE think to do, anions TAKE elections from others, which is a NEGATIVE thing to do...make any sense?
