Origin of hydrogenFrench hydrogène (see hydro- and -gen): coined (1787) by L. B. Guyton de Morveau (1737-1816), French chemist, in reference to the generation of water from the combustion of hydrogen
The element hydrogen on the periodic table.
- 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.
The definition of hydrogen is a gaseous element that has no color or odor and is flammable.
Facts About Hydrogen
An example of hydrogen is one of the elements in water.
Origin of hydrogenFrench hydrogène Greek hudro- hydro- French -gène -gen
From French hydrogène, coined by Louis-Bernard Guyton de Morveau, from Ancient Greek ὕδωρ (hudōr, “water”) + γεννάω (gennaō, “I bring forth”).
- The gas contains a certain amount of hydrogen and oxides of carbon, also traces of nitrogen.
- Dalton believed that the molecules of the elementary gases consisted each of one atom; his diagram for hydrogen gas makes the point clear.
- By the addition of sulphuretted hydrogen to the nitriles, or by the action of phosphorus pentasulphide on the acid-amides.
- Metallic cobalt may be obtained by reduction of the oxide or chloride in a current of hydrogen at a red heat, or by heating the oxalate, under a layer of powdered glass.
- For the quantitative determination of cobalt, it is either weighed as the oxide, C0304, obtained by ignition of the precipitated monoxide, or it is reduced in a current of hydrogen and weighed as metal.
