Hydrogen is a gas at standard temperature and pressure.
Hydrogen is a gas in normal conditions.
Dark energy is believed to make up about 73% of the mass of the Universe; dar matter about 23%; and normal matter - the kind we know most about - about 4%. In the case of normal matter, most of it is still in the form of hydrogen.

Helium, hydrogen, and air are gases.
Metallic sodium or potassium reacts violently with water and may cause an explosion, if the hydrogen that is released by the reaction has the right proportion to the oxygen in the air.
Elemental hydrogen is a gas at normal environmental temperatures. At extremely low temperatures or extremely high pressure, it can become a liquid and even a solid.

More than 74% of the matter in the universe is hydrogen, so when a star forms and collects surrounding matter most of that matter will be hydrogen. It is a simple matter of the availability of different elements.
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%
