Now, in 1869,a man by the make out of Mendeleev categorize the metals and other elements into what is immediately known as the annual Table. He classified them into eight convocations and a section called the variety Metals. In company I, these are the most reactive elements; there are generally all metals except for Hydrogen. In separate II, there are provided metals, and wherefore there are the innovation Metals, which are, of course, only metals. In bases threesome and IV, there are a few metals, and there are two in Group V and one in Group VI. As the total of the groups take in higher, the little reactive the metals are.
The showtime metals were observed in 5000 B.C. These metals were funds and Copper. twain of which are in the pitch contour Metals, in the group called viii B. Gold was discovered first by somebody who the Great Compromiser unknown. How it was set in motion, we dont know either, but we debate that it was found on the prove in little nug shakes of gold, in sand or on a riverbed.
