Barium Barium is a chemical element with symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. The hydroxide, known in pre-modern history as baryta, does not occur as a mineral, but can be prepared by heating barium carbonate.

- Barium is a soft metal belonging to the alkaline earth metals group. It is silvery-white and oxidizes very easily. Its chemical composition resembles calcium [See Periodic Table of the Elements]. Barium is generally kept under an oxygen-free liquid such as petroleum. It can be decomposed after exposure to water or air.

Barium X-Rays (Upper and Lower GI) What are barium X-rays? A barium X-ray is a radiographic (X-ray) examination of the gastrointestinal (GI) tract. Barium X-rays (also called upper and lower GI series) are used to diagnose abnormalities of the GI tract, such as tumors, ulcers and other inflammatory conditions, polyps, hernias, and strictures.

Barium Chemical compounds. Barium is too reactive as a metal, so it is not found in the earth as a metal. It is found in chemical compounds. Barium only occurs in one oxidation state: +2. Most barium compounds are colorless.

General Chemistry/Print version Barium is an element in Group 2, so it has two valence electrons, and that it's charge is 2+. Hydroxide is a polyatomic negative ion with a valency of 1, and that it's charge is 1-. As barium is a metal while hydroxide is a non-metal, they combine to form an ionic compound. To form a neutral compound, balance the positive and negative charges by applying LCM,and the number of positive and negative charges must be equal. Ba^(2+) and (OH)^(2-) Ba^(2+) (OH)^(2-) (OH)^(2-) As seen from above, one barium ion and two hydroxide ions form barium hydroxide.

How Are Elements Grouped? Alkali metals: The alkali metals make up Group 1 of the table, and comprise lithium (Li) through francium (Fr). These elements have very similar behavior and characteristics. Hydrogen is Group 1, but it exhibits few characteristics of a metal and is often categorized with the nonmetals.lkali metals: The alkali metals make up Group 1 of the table, and comprise lithium (Li) through francium (Fr).

Appendicitis Symptoms, Causes, Treatments, and Surgery Test Overview. A barium enema is an X-ray exam of the large intestine (colon and rectum). It may also be called a lower gastrointestinal (GI) exam. The test is used to help find diseases and other problems that affect the large intestine. The colon is filled with a contrast material that contains barium so that the intestine can be seen on an X-ray.

TERBIUM Overview. Terbium is classified as a rare earth element. The term is misleading because terbium is more common than metals such as silver and mercury. The name rare earth meant something else to early chemists. It was used because the rare earth elements were very difficult to separate from each other.

Lanthanum Lanthanum is the first element and prototype of the lanthanide series. In the periodic table, it appears to the right of the alkaline earth metal barium and to the left of the lanthanide cerium. Lanthanum is often considered to be a group 3 element, along with its lighter congeners scandium and yttrium and its heavier congener, the radioactive actinium, although this classification is sometimes disputed.

- Sources of barium. Barium can only be found combined with other elements, typically 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 chlorate.

Barium Barium is reactive, and if you put pure barium metal in the air, it will react with oxygen. At first it will turn black, then white as barium oxide is formed. Barium reacts with water to make barium hydroxide and hydrogen gas. Barium also reacts very fast with acids to make a barium salt and hydrogen.

Exam Preparation A barium enema, or lower gastrointestinal (GI) examination, is an X-ray examination of the large intestine (colon and rectum). The test is used to help diagnose diseases and other problems that affect the large intestine. To make the intestine visible on an X-ray picture, the colon is filled with a contrast material containing barium. This is done by pouring the contrast material through a tube inserted into the anus.
