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.

The noble gas configuration Ne3s² indicates that the element has the same electron configuration as neon, followed by two additional electrons in the 3s orbital. This corresponds to the element magnesium (Mg), which has an atomic number of 12. Therefore, magnesium has the configuration of 1s² 2s² 2p⁶ 3s², reflecting its placement in group 2 of the periodic table.
