The Reactivity of Metals and Their Discovery

Metals argon elements that have certain properties and oppose with several divers(prenominal) things. whatever 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. many a(prenominal) metals be good conductors of heat and electricity, and they ar m aloneeable and ductile. tractable means that the metal can be formed into a certain shape and it will assay in the analogous shape, and ductile means that they can be formed and regulate into wires. Metals are solids (except for mercury and gallium), and they tend to be very sound and can hold big great deal and w eighters. Now, in 1869,a man by the name of Mendeleev categorize the metals and other elements into what is straight 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 reactive elements; there are generally all metals except for Hydrogen. In Group II, there are provided metals, and consequently there are the Transition Metals, which are, of course, only metals. In Groups terzetto 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 less(prenominal) 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 eight-spot B. Gold was discovered first by somebody who corpse unknown. How it was found, we dont know either, but we believe that it was found o n the drop anchor in little nuggets of gold! , in sand or on a riverbed. Gold is found as a inhering element, which means that it is... If you want to get a generous essay, ensnare it on our website: OrderEssay.net
