![]() Brazil nuts can contain up to 1% of barium, as well as some selenium (also toxic in excess), and should be consumed with moderation 3. Despite this toxicity, barium uptake and accumulation has been observed in some plants the green algae Chlorophyta even seems to need barium to grow well, but its role remains unclear 2. ![]() In contrast its carbonate counterpart, which dissolves in stomach acid, is put to use in rat poison. Although barium ions are toxic - they can severely interact with the calcium and potassium metabolic reactions, inducing cardiac irregularities and tremors that can cause paralysis - barium sulfate's insolubility ensures that it can be ingested safely. Indeed, barium sulfate can be introduced in the digestive system, from either end and with notable discomfort, as a contrast agent for X-ray scans to detect stomach or bowel disorders. The most common compounds of Barium are Barite and Witherite. Barium is the fifth element in Group 2 of the periodic table. Barium has atomic number 56 and is represented by the symbol Ba. It includes the atomic number, mass number or sometimes the charge on the element.Baryte is found in many, and varied, materials: as a white pigment in photographic papers as filler in paints, plastics and automobile coatings for smoothness and corrosion resistance in high-density concrete and radiation-shielding cement and even for medical applications. Barium is a soft, silvery alkaline earth metal which is highly reactive in nature, due to its high reactivity it is never found in nature as a free element. In addition to the symbol of an element, additional details are added to the symbol as superscripts or subscripts. Classified as a n alkaline earth metal, Barium is a solid at room temperature. Barium is highly reactive and due to this reactivity of barium, it is never found as a free element in nature. Barium is a chemical element with symbol Ba and atomic number 56. Although many characteristics are common throughout the group, the heavier metals such as Ca, Sr, Ba, and Ra are almost as reactive as the. Barium is an alkali metal compound, it is a silvery and soft metal. The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals. Its abundance is estimated to be about 0.05 percent. Barium is a group 2 element it is the fifth element in group 2 of the periodic table. Barium is the fourteenth most abundant element in the Earths crust. ![]() Barium is a chemical element, the atomic number of barium is 56. For example, the symbol for lead is Pb and it is derived from the Latin name of lead with is plumbum, the symbol for tungsten is W and it is derived from the German name of tungsten which is Wolfram etc. There are many sources from which the symbols are derived, it includes Greek name of an element or German name etc. The chemical symbol of an element usually consists of one or two letters from the Latin alphabet and the first letter is always capital. The chemical symbol is used to represent an atom or an element. The first letter of every chemical symbol is a capital letter and the second letter is a small letter. Barium is a metallic element, soft, and when pure is silvery white it belongs to the alkaline earth group, chemically resembling calcium. Hint: The chemical symbol for an element is usually two letters long.
