Answer:
1.
Every element can exist in the 3 basic states: gas, liquid, solid. It is just a matter of enough freezing and high pressure (to solidify gases, even Helium) or enough heat and low pressure (to vaporize metals, even tungsten). At even higher temperatures the gas can ionize, which can be considered a 4th state of matter.
Your question title contains the word "materials", so I would add that for a general material (which is a mixture of various compounds and elements) the 3 states of matter are also sometimes not achievable. For example wood cannot be in gaseous state, because the structure that makes a wood a wood woud decompose.
