Yes, the metallic copper is an element, this means 'of one kind of atoms', it is Cu with atom number 29 in the Periodic Table.
A 'copper' (money piece) is not made of pure copper, it is an alloy, the same like a 'nickel'.
No. Copper is a single element.
yes because, copper is an element
yes!
yes
Plastics are made from more than one element and therefore are compounds.
Element is a substance made up of only one atom that can not be split into two atoms and compound is a substance which contains two or more element chemically combined together.
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
Amount of copper and tins varies from application to application among bronze products. A typical bronze alloy made of copper(90%) and tin(10%).
The atomic weight of nickel lies in between that of cobalt and copper.
No. Copper is a single element.
Yes it is an alloy of copper and zinc.
Copper is a single element.
Medals are made of red brass that is electroplated to the color they want. Brass is an alloy of copper and zinc, so all medals are made of more than one element.
Brass is the alloy between copper and zinc; sometimes other minor alloying elements are added (Pb, Sn, Fe, Al, As, Mn).
Silver but it's more expensive so we tend to use copper more for conducting electricity
No, copper is not a chemical compound. Its a chemical element.A chemical element is a substance made up of atoms of only one type. IE: Copper. Or hydrogen. Or Helium. Or Lithium... (there are ninety two naturally occurring elements, and several more man made ones)
zinc
Silver IS an element. However, silver jewelry will usually have more than one element. Sterling silver is a mix of silver and copper.
Iron is more reactive than copper. In other words, compared to copper, iron is more stable in a compound while copper is more stable as a pure element than iron is.
An alloy is any metal which contains atoms from more than one kind of element. Examples include: brass (made of copper and zinc), bronze (made from copper and tin) and steels (made from iron and a combination of other elements).
Metals are a class of elements. A pure metal is an element. Some metals are alloys, which mean they have more than one metal or element in them. The metal bronze is made of two elements, the metal tin and the metal copper.
