The reactions with bromine and with iodine wolud probably require heat. So, it is epxected that chlorine, Cl 2 bromine, Br 2, or iodine, I 2, would burn to form the dihalides barium(II) chloride, BaCl 2, barium(II) bromide, BaBr 2, and barium(II) iodide, BaI 2 respectively. I expect barium is very reactive towards the halogens, but I've not yet found explicit references to that effect. The reaction is quicker than that of strontium (immediately above barium in the periodic table) but probably slower than that of radium (immediately below barium in the periodic table).īa(s) + 2H 2O(g) → Ba(OH) 2(aq) + H 2(g) Reaction of barium with the halogens The alkaline earth metals make up Group 2 (IIA) of the periodic table. Barium, three places below magnesium in the periodic table is more reactive with air than magnesium.ģBa(s) + N 2(g) → Ba 3N 2(s) Reaction of barium with waterīarium reacts readily with water to form barium hydroxide, Ba(OH) 2 and hydrogen gas (H 2). Barium is a member of the alkaline earth metals. The superoxide BaO 2 apparently is also formed in this reaction. It is used to make a wide variety of products, including television tubes, x-ray machines, and fireworks. Barium oxide is more normally made by heating barium carbonate. Once ignited, barium metal burns in air to give a mixture of white barium oxide, BaO, and barium nitride, Ba 3N 2. ![]() ![]() The surface of barium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Glass, ceramics, and other barium compounds.īarium nitrate: A white crystalline compound that is used in the manufacture ofįireworks, as well as in the production of other barium compounds.īarium meal: An older term for a barium swallow, referring to the use of a bariumsulfate solution to visualize the internal structures of the upper digestive tract.īarium chromate: A yellow crystalline compound that is used as a pigment in paintsĪnd other materials, as well as in the production of other barium compounds.Barium is a silvery white metal. Non-reactive, making it safe for use in the human body.īarium enema: A medical procedure in which a barium sulfate solution is introducedinto the rectum and colon through the anus, followed by X-rays to visualize the internalīarium swallow: A medical procedure in which a barium sulfate solution is swallowed,followed by X-rays to visualize the internal structures of the upper digestive tract.īarium oxide: A white or yellowish compound that is used in the manufacture of glassand ceramics, as well as in the production of other barium compounds.īarium chloride: A white crystalline compound that is used in the production of otherīarium compounds, as well as in the manufacture of pigments and dyes.īarium titanate: A ceramic material that is used in the production of capacitors,transducers, and other electronic components.īarium carbonate: A white crystalline compound that is used in the production of It is very reactive and in compounds always has valence 2. ![]() Here are some key terms anddefinitions related to barium:īarium sulfate: A white crystalline compound that is commonly used as a contrastmedium in medical imaging tests such as X-rays and CT scans. barium, Chemical element, one of the alkaline earth metals, chemical symbol Ba, atomic number 56. Silvery-white metal that is highly reactive with water and air. Barium is a chemical element with the symbol Ba and atomic number 56.
