nickel and copper are elements that can be magnetized
No - copper and iron are two separate elements. One does not contain any of the other.
They are elements. However, pure iron, gold and copper are produced from naturally occuring ores. In that respect, they are produced.
compound
Iron displace elements with a lower reactivity than its own; copper is an example.
By the the intermediate of chemical reactions; an example is the reaction of copper sulfate with iron (Fe is more reactive).

Formation of some compounds by chemical reactions
No, they're neither. They're elements rather than compounds, and are metals so they're inorganic.
Neither. It is an object. It may be made of elements or compounds like Copper, Iron or Zinc.
no both iron and silicon are elements. chemical compounds aretwo or more elements.
Nitrogen and oxygen are nonmetals.Copper oxide and sodium chloride are compounds, not elements.
when iron nails are kept in a beaker containing copper sulphate displacement reaction takes place.Iron is more reactive than copper so it displaces copper from the copper sulphate solution.Thus it becomes iron sulphate+copper
Neither. It is an object. It may be made of elements or compounds like Copper, Iron or Zinc.
No. Copper and Iron are both elements and are made up of atoms of the pure element.
