Hydrogen

Basic properties of Hydrogen

Hydrogen has atomic number of 1 as shown in the periodic table. The symbol of Hydrogen is H. The atomic weight of Hydrogen is 1.00794 and the melting point of Hydrogen is -255.34°C. Hydrogen has a boiling point of -252.87°C. Hydrogen is a colorless, odorless, tasteless gas. Hydrogen is the lightest element and simplest chemical element. Having atomic number of 1, Hydrogen is the most abundant element in the universe.

Hydrogen is the nuclear fuel consumed by the sun and other stars to produce energy. Although, 70% of the universe is composed of hydrogen, hydrogen constitutes only 0.87%  of the earth 's mass. Most of the hydrogen found on earth is associated with Oxygen. Water, for example, is 11% hydrogen by mass and is the most abundant hydrogen compound. Hydrogen is also an important part of petroleum, cellulose, starch, fats, alcohols, acids, and a wide variety of other materials.

Where does the name Hydrogen come from?

The name Hydrogen is taken from the Greek hydro + genes (gennao) meaning water generator.

Who discovered Hydrogen chemical element?

Hydrogen is isolated and identified as an element by an English chemist Henry Cavendish (1731-1810) in 1766. Henry Cavendish first isolated pure hydrogen and distinguished it from other gases. Because hydrogen produces water when burned in air, the French chemist Lavoisier gave hydrogen its name. Hydrogen means water producer.
