The Reactivity of Metals and Their Discovery

Metals argon elements that have certain properties and respond 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. more metals be good conductors of heat and electricity, and they atomic number 18 m eacheable and ductile. pliable 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 influence into wires. Metals are solids (except for mercury and gallium), and they tend to be very well-knit and can hold big great deal and w eightsomes. Now, in 1869,a man by the name of Mendeleev categorize the metals and other elements into what is instantaneously known as the Periodic Table. He classified them into eight convocations and a section called the Transition Metals. In co mpany I, these are the most reactive 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 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. two of which are in the Transition Metals, in the group called eightsome B. Gold was discovered first by somebody who b ody unknown. How it was found, we dont know! either, but we believe that it was found on the terra firma in little nuggets of gold, in sand or on a riverbed. Gold is found as a indispensable element, which means that it is... If you want to get a generous essay, redact it on our website: OrderCustomPaper.com
