Welcome to "A Visual Interpretation of The Table of Elements", the most striking version of the periodic table on the web. Cobalt was also used to colour glass in the Chinese Tang dynasty from 618 AD. Chemistry in its element is brought to you by the Royal Society of Chemistry and produced by. This give us the (correct) configuration of: 1s2 2s2 2p6 3s2 3p6 3d10 4s1. When cobalt is combined with other metals its strength allow a range of super alloys to be created. As you can probably guess from the name of the region in Zambia - the Copperbelt, cobalt is mined as a secondary product to copper that is dominant in the ore of this region. It is defined as being the charge that an atom would have if all bonds were ionic. Unabbreviated electronic configuration of neutral Cobalt. Cobalt has a magnetic permeability around 2/3 that of iron. As you can imagine this colour change due to the presence of water is highly useful, warranting cobalt chloride an ideal moisture indicator. Some elements exist in several different structural forms, called allotropes. This is where the artist explains his interpretation of the element and the science behind the picture. Cobalt(II) chloride is often used in humidity indicators because in dry form it is blue and when hydrated it is pink. So cobalt; giving joy in an array of beautiful colours, but also ultra strong, hard and magnetic. The atomic number of each element increases by one, reading from left to right. An integrated supply risk index from 1 (very low risk) to 10 (very high risk). It’s Elemental - The Periodic Table of Elements. The b-form is dominant at temperatures under 400°C, while the a-form predominates at higher temperatures. More recently the creation of rare-earth magnets have given us much stronger, harder, permanent magnets than Alnico magnets. It is given by the ratio of the shear stress to the shear strain.
