 Okay, let's try another one so the next one is magnesium so mg so again I really like to do the electron configuration first So let's just go ahead and do that and you get it remember from the periodic table. So 1s 2 2s 2 2p 6 3s 2 I know the problem doesn't ask for that It helps me out and it really makes it really easy. So It says list the total number of electrons for magnesium. So total number of electrons. You just count these out So six plus four ten plus two That's the valence electrons and if you wanted to know the inner
