Hint: Hydrogen is a colorless gas depending on the production type, different colors are assigned to the hydrogen. Green hydrogen is produced by electrolysis of water, using only electricity from renewable energies. It is odorless, nonmetallic, tasteless, highly flammable gas. It has an atomic mass of , which makes hydrogen the lightest element on the periodic table.
Complete answer: Hydrogen is the chemical element with the symbol $H$ and atomic number $1$. With a standard atomic weight of $1.008$, hydrogen is the lightest element in the periodic table. Hydrogen is the most abundant chemical substance in the universe, constituting roughly $75\% $ of all baryonic mass.$1.00794amu$
At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
Hydrogen has no carbon; it does not radiate this light and heat. It has a spectrum consisting of four emission lines within the visible range. Because it is so pale and gives off little heat a hydrogen flame is almost invisible and unnoticeable under common outdoor conditions, and there is a real industrial hazard of people walking unknowingly into a hydrogen flame.
So, the correct answer is (B) false.
Note:
Hydrogen is transparent to visible light, to infrared light, and to ultraviolet light to wavelengths below $1800$. Because its molecular weight is lower than that of any other gas, its molecules have a velocity higher than those of any other gas at a given temperature and it diffuses faster than any other gas.
