Matter can be pressed in case of a. solid b. gas c. liquid d. solid and liquid​

I not sure if this is right but maybe b since its particles is more spread out?

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.
