It will bond in pairs.

It will only be a solid.

It will be one electron short of a full valence.

It is C, right?

aaronq · Answer

C is true, group 17 have 7 valence electrons (they need 8)

B is not true, any element can be a solid, gas or liquid depending on the environment (T, P, etc.)

D is not true either, group 17 elements won't necessarily have $3p^5$ has the valence electrons. For example, bromine ends on $4p^5$... it's true that they will all end on a $Xp^5$ though.
