How do I figure out how many neutrons there are in this, and I need help with electron config?

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.

    Part 2 answer:

    1s^2 2s^2 2p^6

    it has lost two electrons, hence the +2 charge.

    Note the noble gas configuration

    protons and neutrons are the same amount, so there are 24 neutrons.
