Answer: Magnesium atom looses 2 electrons to obtain the noble gas structure.
Explanation:
Atomic number of magnesium is 12. Electronic configuration of magnesium :
![[Mg]=1s^22s^22p^63s^2](https://tex.z-dn.net/?f=%5BMg%5D%3D1s%5E22s%5E22p%5E63s%5E2)
In the periodic table, the nearest noble gas to magnesium element is Neon with atomic number 10.
![[Ne]=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BNe%5D%3D1s%5E22s%5E22p%5E6)
So, in order to obtain noble gas electronic configuration the magnesium atom will loose 2 electrons.
![[Mg^{2+}]=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BMg%5E%7B2%2B%7D%5D%3D1s%5E22s%5E22p%5E6)
