Detailed explanation-1: -Uses of Barium Its compounds are used by oil and gas industries to make drilling mud. Drilling mud simplifies drilling through rocks by lubricating the drill. Barium compounds are also used to make paint, bricks, tiles, glass, and rubber. Barium nitrate and chlorate give fireworks a green colour.

Detailed explanation-2: -The Ba2+ ion and the soluble compounds of barium (notably chloride, nitrate, hydroxide) are toxic to humans. Although barium carbonate is relatively insoluble in water, it is toxic to humans because it is soluble in the gastrointestinal tract.

Detailed explanation-3: -The primary commercial source of barium is baryte (also called barytes or heavy spar), a barium sulfate mineral. with deposits in many parts of the world. Another commercial source, far less important than baryte, is witherite, barium carbonate. The main deposits are located in Britain, Romania, and the former USSR.

Detailed explanation-4: -Barium is a naturally occurring alkaline metalloid element with atomic symbol Ba, atomic number 56, and atomic weight 137 that is only found in combination with other elements, typically barite (barium sulfate) and witherite (barium carbonate), or chemicals.
