History
Barium (Greek barys, meaning "heavy") was first identified in 1774 by Carl Scheele and extracted in 1808 by Sir Humphry Davy in England. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly Carl Wilhelm Scheele (9 December 1742 &ndash 21 May 1786 was a German - Swedish pharmaceutical chemist born in Stralsund, Western Pomerania, Sir Humphry Davy 1st Baronet FRS MRIA (17 December 1778 &ndash 29 May 1829 was a British Chemist and inventor England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland The oxide was at first called barote, by Guyton de Morveau, which was changed by Antoine Lavoisier to baryta, from which "barium" was derived to describe the metal. Louis-Bernard Guyton de Morveau (also Guyton-Morveau after the French Revolution; January 4, 1737 &ndash January 2, 1816
Occurrence
Because barium quickly becomes oxidized in air, it is difficult to obtain this metal in its pure form. It is primarily found in and extracted from the mineral barite which is crystallized barium sulfate. A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition a highly ordered atomic structure and specific Baryte ( Ba[[Sulfur S]] O 4 is a Mineral consisting of Barium sulfate. Because barite is so insoluble, it cannot be used directly for the preparation of other barium compounds. Instead, the ore is heated with carbon to reduce it to barium sulfide[1]
The barium sulfide is then hydrolyzed or reacted with acids to form other barium compounds such as the chloride, nitrate, and carbonate. Barium sulfide is the Chemical compound with the formula Ba[[Sulfur S]] Carbon (kɑɹbən is a Chemical element with the symbol C and its Atomic number is 6 Barium sulfide is the Chemical compound with the formula Ba[[Sulfur S]] Carbon dioxide ( Chemical formula:) is a Chemical compound composed of two Oxygen Atoms covalently bonded to a single Barium Chloride is the ionic Chemical compound with the formula BaCl2 Barium nitrate with Chemical formula Ba( N[[oxygen O]]32 is a salt of Barium and the Nitrate Ion. Barium carbonate ( Ba[[Carbonate CO]]3 also known as witherite, is a Chemical compound used in Rat poison, Bricks
Barium is commercially produced through the electrolysis of molten barium chloride (BaCl2) Isolation (* follow):
Compounds
The most important compounds are barium peroxide, barium chloride, sulfate, carbonate, nitrate, and chlorate. In chemistry and manufacturing electrolysis is a method of separating chemically bonded elements and compounds by passing an Electric current Barium Chloride is the ionic Chemical compound with the formula BaCl2 A cathode is an Electrode through which (positive Electric current flows out of a polarized electrical device The electron is a fundamental Subatomic particle that was identified and assigned the negative charge in 1897 by J An anode is an Electrode through which Electric current flows into a polarized electrical device This page is about the physical properties of gas as a state of matter Barium sulfate is a white crystalline solid with the chemical formula BaSO4 Barium carbonate ( Ba[[Carbonate CO]]3 also known as witherite, is a Chemical compound used in Rat poison, Bricks Barium nitrate with Chemical formula Ba( N[[oxygen O]]32 is a salt of Barium and the Nitrate Ion. Barium chlorate is a white crystalline solid. It is an Irritant, and if consumed can cause nausea vomiting and diarrhoea
Isotopes
Naturally occurring barium is a mix of seven stable isotopes. Naturally occurring Barium ( Ba) is a mix of seven stable Isotopes There are twenty-two isotopes known but most of these are highly Radioactive Isotopes (Greek isos = "equal" tópos = "site place" are any of the different types of atoms ( Nuclides There are twenty-two isotopes known, but most of these are highly radioactive and have half-lives in the several millisecond to several minute range. Radioactive decay is the process in which an unstable Atomic nucleus loses energy by emitting ionizing particles and Radiation. Half-Life (computer-game page here It's already listed in the disambiguation page The only notable exceptions are 133Ba which has a half-life of 10. 51 years, and 137mBa (2. 55 minutes).
Precautions
All water or acid soluble barium compounds are extremely poisonous. Solubility is the characteristic Physical property referring to the ability of a given substance the Solute, to dissolve in a Solvent. In the context of Biology, poisons are substances that can cause damage, Illness, or Death to Organisms usually by At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea and paralysis. The nervous system is a Network of specialized cells that communicate information about an animal's surroundings and itself Anxiety is a physiological and psychological state characterized by Cognitive, Somatic, Emotional and Behavioral components Dyspnea or dyspnoea (pronounced disp-nee-ah, IPA /dɪsp'niə/ from Latin dyspnoea, from Greek dyspnoia from Paralysed redirects here For other uses see xx Paralysed (disambiguation Paralysis is the complete loss of Muscle function This may be due to its ability to block potassium ion channels which are critical to the proper function of the nervous system. In the field of Cell biology, potassium channels are the most widely distributed type of Ion channel and are found in virtually all living organisms
Barium sulfate can be taken orally because it is highly insoluble in water, and is eliminated completely from the digestive tract. Barium sulfate is a white crystalline solid with the chemical formula BaSO4 The mouth, buccal cavity, or oral cavity is the first portion of the Alimentary canal that receives food and begins digestion by mechanically breaking up Unlike other heavy metals, barium does not bioaccumulate. Bioaccumulation occurs when an organism absorbs a toxic substance at a rate greater than that at ftudruinsubstance is lost [2] However, inhaled dust containing barium compounds can accumulate in the lungs, causing a benign condition called baritosis. Baritosis is a Benign type of Pneumoconiosis, which is caused by deposition of inhaled Barium dust in the lungs
Oxidation occurs very easily and, to remain pure, barium should be kept under a petroleum-based fluid (such as kerosene) or other suitable oxygen-free liquids that exclude air. Redox (shorthand for reduction-oxidation reaction describes all Chemical reactions in which atoms have their Oxidation number ( Oxidation state Kerosene, sometimes spelled kerosine in scientific and industrial usage is a Combustible Hydrocarbon liquid Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the
Barium acetate could lead to death in high doses. Marie Robards poisoned her father with the substance in Texas in 1993. She was tried and convicted in 1996.
