questions about barium?

Question

where is barium found on the earth? is it a rare element? what ways does man use barium? and what is it used for?

Answer 1

barium is never found in nature because of its reactivity with the air. It is extracted from the mineral barite



its uses are: drilling oil wells

good for x-rays

useful rat poison

used in making bricks

used in glassmaking

used in medicine



it shouldn't be too rare because it's used in a lot of things

used on the tubes of vacuum cleaners to get in all the dirt and stuff

used for fireworks

used for welding railway tracks

Answer 2

Barium is an alkaline earth metal. It generally loses two electrons to have a charge of 2+. It is a soft silvery metal, that is lustrous. It is hightly reactive with H2O and air. Therefore, it is not found in it pure form in the earth. It is commonly found as barium peroxide, barium chloride, barium sulfate, barium carbonate, barium nitrate, and barium chlorate.





From wikipedia:

"Barium has some medical and many industrial uses:



Barium compounds, and especially barite (BaSO4), are extremely important to the petroleum industry. Barite is used in drilling mud, a weighting agent in drilling new oil wells.

Barium sulfate is also a good X-ray absorber, used in X-ray diagnostic work for obtaining images of the digestive system ("barium meals" and "barium enemas").

Barium carbonate is a useful rat poison and can also be used in making bricks. Unlike the sulfate, the carbonate disolves in stomach acid, allowing it to be poisonous.

An alloy with nickel is used in sparkplug wire.

Barium oxide is used in a coating for the electrodes of fluorescent lamps, which facilitates the release of electrons.

The metal is a "getter" in vacuum tubes, to remove the last traces of oxygen.

Barium carbonate is used in glassmaking. Being a heavy element, barium increases the refractive index and luster of the glass.

Barite is used extensively in rubber production.

Barium nitrate and chlorate give green colors in fireworks.

Impure barium sulfide phosphoresces after exposure to the light.

Lithopone, a pigment that contains barium sulfate and zinc sulfide, is a permanent white that has good covering power, and does not darken in when exposed to sulfides.

Barium peroxide can be used as a catalyst to start an aluminothermic reaction when welding rail tracks together. It can also be used in green tracer ammunition."

Answer 3

1 place to find it-Barium (Greek "barys" meaning "heavy") was first identified in 1774 by Carl Scheele and extracted in 1808 by Sir Humphry Davy in ENGLAND



you can say rare-Because barium quickly becomes oxidized in air, it is difficult to obtain this metal in its pure form

Answer 4

Barium (IPA: /ˈbɛːriəm/) is a chemical element in the periodic table that has the symbol Ba and atomic number 56. Barium is soft silvery metallic alkaline earth metal. It is never found in nature in its pure form due to its reactivity with air. Its oxide is historically known as baryta but it reacts with water and carbon dioxide and is not found as a mineral. The most common naturally occurring minerals are the very insoluble barium sulfate, BaSO4 (barite), and barium carbonate, BaCO3 (witherite).

Answer 5

Barium is found as a mineral in ore in the earth. It is not really rare. It is used in medicine because it is radio opaque(xrays do not go through it) for xrays of soft tissue such as the intestines, barium enema.
