Metal vs gas is a poor choice of dichotomy: every element is a gas at the right temperature and pressure.

Astronomers presumably mostly think about matter in the form of a star, in which presumably all the hydrogen and helium would be in some sort of plasma state, and perhaps all the “metals” would be too.
