Is there an element 104?
rutherfordium (Rf), an artificially produced radioactive transuranium element in Group IVb of the periodic table, atomic number 104.
Is cobalt and nickel the same?
Cobalt is a metal that is commonly found in soil and sea water, as well as in various industrial compounds. It is usually found in association with another metal, nickel. Most alloys and salts contain both these metals, their separation being too costly to be feasible.
Is cobalt in nickel?
Most nickel, iron, sulfur, and little isomorphism cobalt form pentlandite, while most cobalt, some nickel, arsenic, and sulfur form cobaltite.
Why is cobalt named after a goblin?
The element cobalt’s name comes from the German word kobold, meaning goblin or evil spirit. It was named by miners in 16th century Saxony who thought they had found deposits of silver but had actually found cobalt arsenide.
What is cobalt mineral?
Cobalt (Co) is a bluish-gray, shiny, brittle metallic element. There are no significant minerals of cobalt. It is rare and obtained mostly through refining of nickel ore. It is used in superalloys for jet engines, chemicals magnets, and cemented carbides for cutting tools.
What group does cobalt belong to on the periodic table?
Cobalt (Co), chemical element, ferromagnetic metal of Group 9 (VIIIb) of the periodic table, used especially for heat -resistant and magnetic alloys. Properties of cobalt. The periodic table is made up of 118 elements.
How was cobalt first discovered?
Suspecting that the core of the material was in fact a previously unknown element, Brandt tested his theory on an ore from Sweden, and separated the metal via fire assay, and isolated the same substance that those German miners had named. Brandt stuck with the miners’ name for the material, and called the newly discovered element cobalt.
How many protons and electrons does cobalt have?
Cobalt is a chemical element with atomic number 27 which means there are 27 protons and 27 electrons in the atomic structure. The chemical symbol for Cobalt is Co. Cobalt is found in the Earth’s crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron.
What is the chemical name of green cobalt II oxide?
Green cobalt (II) oxide (CoO) has rocksalt structure. It is readily oxidized with water and oxygen to brown cobalt (III) hydroxide (Co (OH) 3 ). At temperatures of 600–700 °C, CoO oxidizes to the blue cobalt (II,III) oxide (Co 3 O 4 ), which has a spinel structure. Black cobalt (III) oxide (Co 2 O 3) is also known.
