It is an odourless gas.
Hydrogen has no odor or taste.

Hydrogen has no color, no odor, and no taste. One of the things it does have is high flammability.
Physical.Added:Odor is by many considered as chemical interaction with nasal odor receptors, though this is still under dispute.I, personally, would be more of the 'physical' odor perception, because the odor-creating molecules (eg. in perfume) do not change at all while being 'percepted' in your nose.However there are also undoubtly pure chemical odor perceptions, like those of (gaseous) 'acids', 'ammonia', 'formalin' and hydrogen sulfide.
Odor results from chemical reactions. Sensors in your nostrils bind with specific compounds in the air to detect scents. But this is not to be confused with the fact that odor is a physical property.

Nitrogen, Hydrogen Methane and Oxygen. The methane and hydrogen causes the odor. The Nitrogen causes the sound.
Gases containing sulfur give a bad odor.
Yes, Hydrogen sulfide is present in trace amounts in blood and intracellular fluid. it also contributes to the odor of flatulence.

Hydrogen peroxide is useful but is too expensive.
Hydrogen bromide (HBr) is a compound because it consists of two elements (hydrogen and bromine) that has been chemically combined to form a new substance. It is a colourless gas with an acrid odor at room temperature.
