The Reactivity of Metals and Their Discovery

Metals argon elements that have certain properties and controvert with several divers(prenominal) things. whatsoever metals react with oxygen, some with water, some with hydrochloric acid, and several another(prenominal)(a) things. Also, some elements react more readily than others, and they react at different speeds. some metals be good conductors of heat and electricity, and they ar mall(a)eable and ductile. pliant means that the metal can be formed into a certain shape and it will assay in the aforesaid(prenominal) shape, and ductile means that they can be formed and do into wires. Metals be solids (except for mercury and gallium), and they tend to be very salutary and can hold big great deal and w eights. Now, in 1869,a man by the name of Mendeleev categorize the metals and other elements into what is now known as the Periodic Table. He classified them into eight convocations and a section called the Transition Metals. In company I, these are the most reac tive elements; there are generally all metals except for Hydrogen. In Group II, there are provided metals, and thus there are the Transition Metals, which are, of course, only metals. In Groups terce and IV, there are a few metals, and there are two in Group V and one in Group VI. As the numbers of the groups take in higher, the little reactive the metals are.

The first metals were discovered in 5000 B.C. These metals were funds and Copper. both of which are in the Transition Metals, in the group called viii B. Gold was discovered first by somebody who body unknown. How it was found, we dont know eith er, but we believe that it was found on the ! strand in little nuggets of gold, in sand or on a riverbed. Gold is found as a aboriginal element, which means that it is... If you want to get a generous essay, magnitude it on our website: OrderCustomPaper.com
