Methane has a melting/freezing point of -182.5C and a vaporization/condensation point of -161.6 C. Which substance (A-D) could most closely resemble the molecular behavior
of methane?

AHHH please help

- decrease the number of plants and animals living in the water.

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.
