Barium is important because it helps make a few things that you've most likely used by now. Barium in used in fireworks. It gives fireworks that green color. Barium sulfate can be very useful to doctors to coat the inner lining of the intestines to allow them to examine a patient's digestive system. Before receiving x-rays, a patient may be instructed to drink a chalky barium sulfate liquid, which absorbs a great deal of the radiation emitted by the x-ray machine.This adds contrast to the black-and-white x-ray photo, which helps the doctor make a better diagnosis. This can really help doctors. This is why I think that my element is important and useful in the real world and in everyday life.

1. It oxidizes in air.

2. It reacts in water and forms hydroxide.

3. Peroxide forms when it burns in air.

4. Barium will react with most nonmetals.

Barium is not an extensively used element, but it is used in a few things. Barium is used in drilling fluids for oil and gas wells. All barium compounds are toxic, but barium sulfate is insoluble and so can be safely swallowed. A suspension of barium sulfate is sometimes given to patients suffering from digestive disorders.Barium is a heavy element and scatters X-rays, so as it passes through the body the stomach and intestines can be distinguished on an X-ray. Barium carbonate has been used in the past as a rat poison. Barium nitrate gives fireworks a green color. It is used in paint pigment. It's used in glass and pottery glaze. It's used in vacuum tubes.

a.) Melting point: 1000 K (727°C or 1341°F)

b.) Boiling point: 2170 K (1897°C or 3447°F)

c.) Density: 3.62 grams per cubic centimeter

d.) Abundance in the earth's crust: 0.034%

e.) Isotopes: Barium is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, recently identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks)

Barium is never found in nature, as it reacts with oxygen in the air, it forms barium oxide. Barium can only be found combined with other elements. It's typically combined with sulfate and carbonate. Barium is prepared by electrolysis of barium chloride. The most significant compounds of the element are the peroxide, chloride, sulfate, carbonate, nitrate, and chloride.

Baryta, the term for several barium compounds, was distinguished from lime by German chemist Carl Wilhelm Scheele in 1774. Barium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of molten baryta.

The origin of the name comes from the Greek "barys" meaning heavy. The element is called barium because it was found in barite (barium sulfate) a mineral given its name because of its high density.
