No, sulfur has six valence electrons, while magnesium has two valence electrons.
When magnesium loses its valence electrons, it forms a cation with the atomic structure of neon. This is because it will lose its two valence electrons to achieve a full octet like the nearest noble gas, which is neon.
The element with 2 valence electrons on the third energy level is magnesium. Magnesium has an electron configuration of 2-8-2, with 2 electrons on the outermost energy level.
Magnesium has 2 valence electrons.
