Deuterium Atomic Number

Some properties of normal hydrogen and deuterium

Deuterium (or heavy hydrogen) was an isotope of hydrogen. Deuterium with an admixture of tritium was used as fuel in matter-antimatter reactions aboard starships, like the USS Enterprise-D. It was stored in the deuterium tanks. (TNG: 'Contagion', 'Booby Trap', 'Disaster' okudagrams) During the 22nd century at least, It was considered a highly valuable commodity, and the Enterprise engines. Each are isotopes of hydrogen. Hydrogen nucleus has one proton only. Thus atomic number is one. This determines which element it is; and atomic weight is one.
