20.04.2012Metals are atoms, which can form cations by removing electrons. So they are electropositive. The type of bond forms between metal atoms is called metallic bonding. Metals release electrons in their outer shells and these electrons are dispersed between metal cations. Therefore, they are known as a sea of delocalized electrons.

Metallic Deposits. Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits, however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined. Again, the profit line is dependent on a number of economic factors.
