They have created a complete suite of short videos on every element on the periodic table of elements. The video below is from the University of Nottingham's periodic videos project. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Hexaamminecobalt(III) chloride is the chemical compound with the formula Co(NH 3) 6Cl 3.It is the chloride salt of the coordination complex Co(NH 3) 6 3+, which is considered an archetypal 'Werner complex', named after the pioneer of coordination chemistry, Alfred Werner. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The density is 8.9 grams per cubic centimeter. Cobalt is a chemical element with atomic number 27 which means there are 27 protons in its nucleus. Cobalt has only one isotope found in nature: Symbol The melting point of cobalt metal is 1,493C (2,719F), and the boiling point is about 3,100C (5,600F).

Radioactive isotopes of cobalt tend to have very short half lives, most of which are less than 24 hours.

This isotope is used for radiotherapy, as a medical tracer, and to sterilize medical equipment through irradiation. Melting point is the temperature at which a substance changes from solid to liquid state. Radioactive cobalt-60 is a commonly used medical isotope. Lithium cobalt oxide is one of the lithium oxides commonly used in rechargable lithium batteries. Melting point of steel: 1425-1540 C / 2600-2800 F Melting point of gold: 1064 C / 1947.5 F Melting point of copper: 1084 C / 1983 F Melting point of iron: 1538 C / 2800 F Melting point of lead: 327.5 C / 621 F Melting point of silver: 961 C / 1761 F. Cobalt alloys are used to make items that need high strength and corrosion resistance such as magnets, jet and gas turbine generators, surgical implants, and prosthetics.

Cobalt is most commonly used as part of an alloy though. Pure cobalt metal is sometimes used for electroplating because it is hard and corrosion resistant. Ĭobalt salts have long been used to create the distinctive blue colour for porcelain (Figure 2), as well as for enamel and paints, pottery, and glass. Cobalt blue Chinese porcelain from the 1400s.
