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).
At room temperature hydrogen is a gas.

It is a gas.
Silicon is a solid at room temperature.
Well now, that would depend on what kind of matter you're talking about, wouldn't it. At room temperature (and room pressure) . . . -- Oxygen, nitrogen, and helium are in the gas phase. -- Water, mercury, and grain alcohol are in the liquid phase. -- Iron, sugar, and candle wax are in the solid phase.
At room temperature, Calcium is a soft grey solid.
At normal (room) temperature gold is in solid state of matter (phase).

Carbon at room temperature is solid.
Neptunium is a solid metal at room temperature.

just like you
