Question

How would Mg change to gain a noble gas structure?

lose 2 electrons
gain 6 electrons

Answer 1

Are those the answers
hah because i got a little confused

Answer 2

Answer: Magnesium atom looses 2 electrons to obtain the noble gas structure.

Step-by-step explanation:

Atomic number of magnesium is 12. Electronic configuration of magnesium :

`[Mg]=1s^22s^22p^63s^2`

In the periodic table, the nearest noble gas to magnesium element is Neon with atomic number 10.

`[Ne]=1s^22s^22p^6`

So, in order to obtain noble gas electronic configuration the magnesium atom will loose 2 electrons.

`[Mg^(2+)]=1s^22s^22p^6`
