Amongst the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, and silver-mercury and gold-mercury amalgam. Only gold, silver, copper and the platinum metals occur in nature in larger amounts.Over geological time scales, very few metals can resist natural weathering processes like oxidation, which is why generally only the less reactive metals such as gold and platinum are found as native metals.mongst the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, and silver-mercury and gold-mercury amalgam.

Native elements are minerals that contain only atoms of one type of element. The elements are not combined with other elements. In nature most elements are combined with other elements to form chemical compounds. So, the native elements mineral group contains a relatively small number of minerals. One mineral contains the elements zinc, carbon, and oxygen. 2  The other mineral contains the elements zinc, silicon, oxygen, and hydrogen. 3  Your friend tells you that the minerals are in the same mineral group.
