Two different atoms have four protons each and the same mass. However one has a positive charge while the otheris neutral. Describe what each atomic structure could be listing the number and location all subatomic particles.

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.
