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 element is magnesium with an atomic number 12.The element belongs to the 3rd period, with two valence electrons in the s orbitals. The element is an example of alkaline earth elements or group 2 elements.
The noble gas configuration of magnesium is [Ne] 3s^2. This indicates that magnesium has the same electron configuration as the nearest noble gas, neon, with an outer shell containing 2 electrons in the 3s orbital.
