Introduction to Hydrogen

Hydrogen is the first element of the modern periodic table and lightest among all the elements found in nature. It exists in diatomic form. Hydrogen was discovered by Henry Cavendish in 1776 A.D. The name hydrogen was given by Antoine Lavosier in 1817. Hydrogen is found in free state in very trace quantity. However, it is ninth most abundant element in earth. Hydrogen is found in the core of the sun. Hydrogen is the main cause for the nuclear fusion at the core of the sun.


Hydrogen is derived from the Greek word “hygrogene” in which hydro means water and gene means producer. Hydrogen produces water when burnt with oxygen.
