i dont know what it is Because my teacher asked me the same Question! The phase of hydrogen at room temperature is in a gas state.

Gas. Unquestionably. Consider the alternative: Liquid? Solid? Maybe plasma? Liquid and solid hydrogen only produced in near the absolute temperature. Plasma on the other hand requires enormous temperature and pressure (Sun).
Yes, mercury being one notable exception.
