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.
