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.
