the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

i believe that it is a exoplanet

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