CO ELEMENT FORMULA FREE

Most of the cobalt used in the United States is imported from other countries.Small amounts of cobalt are sometimes used in fertilizers.Too much or too little cobalt in the body can cause health issues.Cobalt-60 is used to create gamma rays which are used to treat cancer and to sterilize medical supplies.Cobalt was the first metal to be discovered since prehistoric times and the first metal with a recorded discoverer.The most common oxidation states are +2 and +3. It is also a component of the vitamin B 12.Ĭobalt gets its name from the German word 'kobalt' which means 'goblin.' Miners gave cobalt ore this name as they were superstitious about mining the ore.Ĭobalt only has one stable isotope that is found in nature: cobalt-59.Ĭobalt exists with oxidations states ranging from -3 to +4. The body uses it to create certain enzymes. He isolated the element and proved that it was the source of the color in blue glass which previously was thought to be from bismuth.Ĭobalt compounds were used throughout ancient history by civilizations such as Ancient China and Rome to make blue glass and ceramics.Ĭobalt is also important for animal life. Other applications for cobalt include batteries, industrial catalysts, electroplating, and powerful magnets.Ĭobalt was discovered by Swedish chemist George Brandt in 1735. Most of the cobalt that is mined is used in superalloys which are very resistant to corrosion and are stable at high temperatures.Ĭobalt is also used as a blue coloring agent in paints, inks, glass, ceramics, and even cosmetics. The majority of cobalt is mined in Africa and is a byproduct of the mining of other metals including nickel, copper, silver, lead, and iron. Carbon Dioxide CO2 CID 280 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety. Cobalt ores include erythrite, cobaltite, skutterudite, and glaucodot.

It forms many compounds with other elements such as cobalt(II) oxide, cobalt(II) fluoride, and cobalt sulfide.Ĭobalt is not found as a free element, but is found in minerals in the Earth's crust. It reacts slowly with oxygen from the air. It can be easily magnetized and maintains its magnetism at high temperatures.Ĭobalt is only somewhat reactive. It is one of the few elements that is naturally magnetic. Under standard conditions cobalt is a hard, brittle metal with a bluish-white color. Water is composed of hydrogen atoms and oxygen atoms chemically bonded in a 2:1 ratio, which leads to the chemical formula for water being written as H 2 O. Cobalt atoms have 27 electrons and 27 protons with 32 neutrons in the most abundant isotope. A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. If we consider the molecular formula for sulfuric acid, H 2SO 4, one of the most widely produced chemicals in the United States, we could conclude that one molecule of H 2SO 4 contains two hydrogen atoms, one sulfur atom, and four oxygen atoms.Cobalt is the first element in the ninth column of the periodic table. We would not write N 3H for ammonia, because that would mean that there are three nitrogen atoms and one hydrogen atom in the molecule. A value of '1' is implied when there is no subscript written after an element.

If there is more than one atom of a specific kind, the number is written as a subscript following the atom.

The number of atoms of each kind is indicated by a subscript following the atom. The arrangement of the elements depends on the particular structure, which is not of concern at this point.
