Hydrogen is a non metal element. Atomic mass of it is 1.0079.
Hydrogen is a non meta element. Atomic mass of it is 2.
Each isotope of each element has an atomic mass number. The atomic mass numbers for hydrogen are 1, 2 and 3. That's because hydrogen has three isotopes. "Regular" hydrogen has a single proton in its nucleus. It's atomic mass is 1. There is also heavy hydrogen, which has a neutron bound to the proton in its nucleus. It's atomic mass is 2. Heavy heavy hydrogen has two neutrons bound together with the proton. It's atomic mass is 3. A link is provided to the Wikipedia article on hydrogen.
The atomic mass of Hydrogen is 1.00794 amu.
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.
The atomic weight (not mass) of hydrogen is [1,00784; 1,00811] or in an abridged form 1,008.
