The Reactivity of Metals and Their Discovery

Metals argon elements that have certain properties and reply with several divers(prenominal) things. roughly 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(prenominal) metals be good conductors of heat and electricity, and they atomic number 18 m wholeeable and ductile. bendable means that the metal can be formed into a certain shape and it will assay in the equivalent shape, and ductile means that they can be formed and molded into wires. Metals are solids (except for mercury and gallium), and they tend to be very good and can hold big great deal and w octettes. Now, in 1869,a man by the name of Mendeleev categorize the metals and other elements into what is at once 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 thence there are the Transition Metals, which are, of course, only metals. In Groups triad 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 slight reactive the metals are.

The first metals were discovered in 5000 B.C. These metals were funds and Copper. twain of which are in the Transition Metals, in the group called octet B. Gold was discovered first by somebody who be unknown. How it was found, w e dont know either, but we believe that it w! as found on the country 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, run it on our website: OrderCustomPaper.com
