copper, silver and carbon are not real ores but could be found as pure elements: carbon as coal, or diamond. Silver as nuggets. Copper as native copper specimen. Iron is almost never found in the free elemental state, and should be extracted from iron ore, which is not iron, but mainly made of iron oxides.
No. A penny is made out of copper-plated zinc.
Dimes minted before 1965 are made of 90% silver and 10% copper. Dimes minted after 1965 are made of a copper core with a outer layer of nickel.
Coins,mobiles and pencils are mostly in our pockets.Coins are made up by silver,copper,zinc.in Mobile copper,silver,steel,gold are found.In Pencils led is used so, the elements which are mostly found in our pockets are copper,zinc,steel,iron, and gold etc.
It is supposed that the Earth core is composed from iron and nickel.
Jewelry can be made from iron, silver, copper, and gold. It is melted down and formed into lovely pieces.
Ill answer them in order of how you asked, gold, silver, iron oxide mixed in a rock with various other minerals, copper and tin

No. Copper and Iron are both elements and are made up of atoms of the pure element.
Dimes are currently made from nickel and copper; they used to be made from silver. They do not have any significant amount of iron in them. (Some minor degree of contamination is always possible.)
Gold was made before copper, silver and bronze. Making gold was easier and took a lot less time.
No, it means chariots with silver and copper on them.
granite, marble, sandstone, iron, copper, cold ,silver ,ruby, emarald, sapphhire, diomand,etc.
Silver dollars from 1794 to 1935 were made of 90% silver and 10% copper, neither of which are attracted to a magnet. Only ferrous metals such as steel and iron, and certain other metals such as nickel are attracted to a magnet.
Ironman's suit is not made of copper.
the metal on which electroplating is to be done is taken as cathode ( negative electrode) . the metal of which electroplating is to be done is taken as anode ( positive electrode) and the salt solution of the metal of which electroplating is to be done is taken as electrolyte . example- if we want to electroplate iron with copper then iron is taken as cathode and copper is taken as anode and electrolyte is copper sulphate.Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes. This is done through the use of copper in a copper sulfate bath.
