What's the atomic structure, including the electron shells, of a magnesium atom 24/12 Mg?

This question is on my Physical Science Semester Exam and I need help! The 24 and 12 are to the left of the equation and the 24 is on top... I figured out a little bit of it but I can't figure out the rest and then figure out how to transfer it to words! Can anyone help me? It's due reeealllyyy soon so any help, fast, would be great! Thanks!
