The element is sulfur (S, #16). [Ne] means neon is the nearest noble gas with a lower atomic number. The 3s23p4 means electrons have filled the 3s2 sublevel, and 4 out of 6 possible locations in the 3p sublevel are occupied. Adding the number of electrons to neon (2+4+10) gets you 16, which identifies the element. Sulfur is in period 3, which corresponds to the unfilled level of electrons. The group is 16(6A). Sulfur is considered a p-block element, because its valence electrons partially fill the p sublevel.
Ne3s2 doesn't represent a valid element. The symbol for Neon is Ne, and the electron configuration for neon is 1s2 2s2 2p6. The number 3 in front of "Ne" and "S" doesn't follow the typical electron configuration notation.
Since that other guy said no, I'm going to explain why. Since argon has a structure of Ne3s2 3p6 (I think I might have the p and s switched around) that makes a second shell, so it is impossible to share an electron field with another molecule since there are no spaces for electrons to attach. Even if you put it with a highly reactive element such as sodium or hydrogen, it will not react.
The "ne" in ne3s2 3p1 refers to the element Neon, which is a chemical element with the atomic number 10. The notation ne3s2 3p1 specifies the electron configuration of Neon, where the "ne3s2" denotes 3 electrons in the 3s orbital and "3p1" denotes 1 electron in the 3p orbital.
Magnesium, Mg.
