Metalwork - Materials - Periodic Table Of the Elements

If you scroll down further you can use the Periodic Table to find out more information about each Element, the information will pop up in below, but first some history of the Periodic Table. Elements such as tin, copper, silver and gold have been around for a long time, but the first actual scientific discovery of an Element was made by Hennig Brand in 1649 when he came across phosphorous. For another 200 years, scientific information about the properties of elements was collected by scientists. By the time 1869 came around, 63 elements had been discovered in total. Scientists began to see that there were patterns in the properties of the Elements and so began to develop tables that classified the Elements that they knew of. In 1869 a Russian by the name of Dmitri Mendeleev published the first Periodic Table of The Elements. This man is seen by many to be the 'father' of the Periodic Table but others feel that a German, Lothar Meyer, should get at least some of the recognition as he had records of his own personal Periodic Table dating to 1864. (It's never happy in paradise !). Mendeleev's table was not totally correct originally and corrections had to be made. There were also a number of Elements missing that had not yet been discovered and so the Periodic Table of the time was far from the same as we know it today. Mendeleev showed the that the Elements are periodic in nature but it took the scientists of the 20th Century to explain why elements recur periodically. The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements, (those from 94 to 102). He rearanged the periodic table by placing the Actinide series below the Lanthanide series. In 1951, Seaborg was awarded the Nobel Prize in chemistry for his work. Element 106 has been named Seaborgium (Sg) in his honor. And now onto the Table itself.... Click on the Elements to get information on them. The Elements shown in yellow are non-metals. The Elements shown in grey are metals, and the Elements shown in red are in the Lanthandine Series. Have fun ....
