I need help with electron configuration and with finding the amount of neutrons...?
Okay, in:
^24 Mg ^2+
protons= 24, electrons= 22, now how do I figure out neutrons?
And...
whenever I'm finding the electron config for Mg,
it is 1s^2 2s^2 2p^6 3s^2.
But what is it whenever I'm looking for electron config of Mg ^2+
?
Or is it not different?
Well if you know any part of these questions, I'd be glad for the help.

I can't remember what the ^24 means, but I think it's either the mass, which wouldn't make sense because then neutrons would be zero, or number of neutrons.
Because the electron config. is 2+, that means you just drop the two on the outermost shell, so just get rid of 3s^2.

I haven't taken Chemistry for 3 years so forgive me if I'm very rusty. I think Neutrons is the same number as protons. also, for the electron configuration, it's almost impossible to do without a periodic table :) whenever there is like 2+ or 1+ anything like that, it just means you have to count the places on the periodic table.. Hope this helps you at least a little.. I know it's kinda vague..
