2+4= 6 valence electrons
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
sulfer
[Ne]3s23p4
8 valence electrons (so do all of the other noble gases)
Silicon.Neon has 10 electrons. Adding 4 more electrons to that gives 14 electrons, and the configuration of [Ne] 3s2 3p2. This configuration belongs to the element silicon.
