Facts About Hydrogen
- An atom of hydrogen is the smallest of all elements that exist.
- Hydrogen is the most plentiful element in the universe.
- An atom of hydrogen is made up of two subatomic particles, one electron and one proton.
- Hydrogen exists in three forms - hydrogen, deuterium, and tritium.
- Tritium is radioactive and is used in the construction and operation of nuclear weapons.
- The combustion of hydrogen is very clean and has little impact on the environment. The byproduct of the combustion of hydrogen and oxygen is water vapor.
- Hydrogen gas was the first fuel used in inflatable aircrafts and Zeppelins, such as the Hindenburg which exploded in 1937.
- Hydrogen is a perfect liquid for cryogenic freezing.
An example of hydrogen is one of the elements in water.
