Fun Facts

  • was discovered by Henery Cavendish in 1766.
  • hydrogen comes from the Greek word Hydro and Gen being water generator.
  • hydrogen is the most abundant element in the universe.
  • 200 hydrogen fuel cars in the United States, but they are mostly located in California.

Hydrogen: a colorless, odorless, highly flammable gas.

Isotopes/abundance

Melting

Point

There are three naturally

occurring isotopes in Hydrogen. The three isotopes are 1H, 2H, and 3H. There is also 4H, but this isotopes is not as stabel as the other three isotopes. There is also deuterium and tritium which is used in nuclear weapons.

Compounds

  • H1: The mass is 1.007825 and the abundance is 99.99.
  • H2: The mass is 2.014102 and the abundance is 0.015
