What is the state of aggregation of matter, in which the elements are found in nature to the environment (solid, liquid, and gaseous)?

mark him as !

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'm assuming that the correct answer is indeed the first one/ "a"..
