Nights with Bryan Crump is also celebrating the chemical elements during their Friday night Sonic Tonic and Element of the Week. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
The atomic number is the number of protons in the nucleus of an atom. Also, by convention, when the symbol of an element contains two letters, the first one is capitalized. The Elemental podcast is celebrating 150 years since the periodic table was first published by Russian chemist Dmitri Mendeleev.įind out more about events during the United Nation’s International Year of the Periodic Table. In the modern periodic table, the elements are listed in order of increasing atomic number. The symbol for Cobalt is Co and not CO because CO can be misunderstood as carbon monoxide(CO). You can subscribe to the Elemental podcast for free, at Apple Podcasts, Spotify, Stitcher and RadioPublic. Chemical Properties of Cobalt Electrochemical Equivalent: 1.0994g/amp-hr Electron Work Function: 5eV Electronegativity: 1.88 (Pauling) 1.7 (Allrod Rochow).

Terbium is never found in nature as a free element, but it is contained. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. It is used to make magnetic alloys, heat-resistant. For the same reason, zinc has been proposed as a salting material for nuclear weapons (cobalt is another, better-known salting material). Symbol Co A silvery-white, hard, brittle metallic element that occurs widely in ores containing other metals. It is a silvery-white, rare earth metal that is malleable, and ductile. Zinc is a chemical element with the symbol Zn and atomic number 30. It very rarely occurs in native form, so it is usually found as part of minerals (e.g.
Professor Allan Blackman from AUT says cobalt is his favourite chemical element as he studied it for his PhD. Terbium is a chemical element with the symbol Tb and atomic number 65. It is an essential trace element in animals as it part of vitamin B 12.įoer a while it was added to beer to help it maintain a frothy head, but when coupled with poor diet and lots of alcohol it led to heart problems known as ‘cobalt-beer cardiomyopathy.’ It is ferromagnetic, which means it can form a permanent magnet.Ĭobalt is responsible for the cobalt blue paint pigment and Bristol blue glass. It was named by miners in 16 th century Saxony who thought they had found deposits of silver but had actually found cobalt arsenide.Ĭobalt (symbol Co and atomic number 27) is a transition metal. The element cobalt’s name comes from the German word kobold, meaning goblin or evil spirit.
