    Barium is a soft, heavy, silver-colored metal element. This element does not have very many uses outside of the laboratory, but it combines easily with other chemicals to form compounds used for important industrial uses. For example, Barium carbonate is used in the manufacture of ceramics and special glass, and also to purify certain chemical solutions. It is also an ingredient in clay slurries, also known as water muds, used in drilling oil wells. Barium titanate is used in sonar detectors and

    as we know it. Without them, many things that we both love and need would be gone. These remarkably diverse yet very similar elements that make up the alkaline earth metals family are: Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). Although this family is often overshadowed by the infamous alkali metals, you will soon learn how spectacular and brilliant these metals really are and their value to human life. The alkaline earth metals are an interesting

    IBS seek help from a gastroenterologist. A gastroenterologist is a doctor who specializes in the digestive system. Tests to diagnose IBS might include lab analyses of feces and barium X-rays of the lower digestive tract. For a barium X-ray, a patient drinks a special kind of liquid drink that contains barium. With the barium, the doctor can see how the liquid flows through the digestive system. A doctor may also perform a sigmoidoscopy. This is an instrument on a long thin tube that is inserted through

Roentgen further observed a surface he had coated with barium Platinocyanide that was placed outside of the cathode discharge tube would still emit light, despite the fact that it was concealed from the light of the discharge. The conclusions that Roentgen came to were that a new type of radiation had passed

    electron current while semi-conductors, such as silicon, have a medium resistance. Conductors, like copper and other metals, have very low resistance, and superconductors, comprised of certain metals such as mercury and ceramics such as lanthanum-barium-copper-oxide, have no resistance. Resistance is an obstacle in the flow of electricity. Superconductors also have strong diamagnetism. In other words, they are repelled by magnetic fields. Due to these special characteristics of superconductors, no
