Some nanostructures can be modelled as an electron confined to a two-dimensional region. Calculate the energy separations in joules, kilojoules per mole, and electronvolts between the levels (a) n1

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

catya that's not even a b or c
