and sometimes affects the environment and humans. Barium are even used for making glass and used in fireworks. Barium is even found in our food. The History Of Barium In 1808 Barium was isolated by an English chemist named Sir Humphry Davy by electrolysis of molten baryta or BaO. But it was discovered in 1779 by Carl Scheele. Barium is classified as an alkaline-earth metal. Its atomic number is 56 and it is the fifth element in group 2.Natural Barium is made up of a mixture of seven stable isotopes
