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.

A good rule of thumb to remember is that compounds containing two non-metals (on the right side of the periodic table, for the most part) are usually COVALENT in bonding nature, while a compound containing a metal and a non-metal (like all 3 you listed here) are IONIC in bonding nature.eport Abuse. metal to non metal is ionic non metal to non metal is covalent anything on the left side (groups 1a 2a and the transition metals) are metals and the right side (4a 5a 6a 7a) are non metals.
