The atomic number of neon is 10, the electronic config. of [Ne]3s2 correspond to the with atomic number 12, namely magnesium.
Additional info is that with only two electrons the element would achieve the octet more reaily by losing them rather than by gaining another 6.
The noble gas configuration of magnesium is [Ne]3s2.
