Is this true :-When metals bond with any other element or compound, it is through ionic bondingAndWhen only non-metals bond, it is through covalent bonding (sharing of electrons)??Please explain your answers!!
switches that are used for 6.6 kv lines are called metal clads.
Hi. Metal clad means a metal has been bonded to the surface. Usually for wear.
An example would be in quarter and dime coins. Until 1965 these were made up of 90 percent silver. When the price of silver went up they removed it from the coins. The coins are copper clad, with a layer of other metal(s) on the outsides to make the coins look silvery. They can be referred to as sandwich coins, as you can see the layers by looking at the sideways edge of a quarter.
