Metals. Gold silver and copper are members of the same group column in the periodic table of elements and therefore have similar chemical properties. In the uncombined state their atoms are joined by the fairly weak metallic bond.These minerals share a common structure type and their atoms are positioned in a simple cubic closest-packed arrangement.Searching for Gold Minerals that Assist in Gold Inclusions of other minerals within gold grains can provide insight into the ore and help geologists gauge which minerals are present in the bedrock source of the gold. mercury lead iron and Precious and Industrial Metals - BloombergGet updated data about gold silver and other metals prices.
