Because copper is a chemical element and contain only identical atoms.
Copper is a pure substance.
Copper metal is an element and thus a pure substance.
No. Copper is an element.
No, a brass screw is not a pure substance. Brass is an alloy made up of copper and zinc, so it is considered a mixture rather than a pure substance.
Yes, elemental copper is considered a pure substance because it consists entirely of copper atoms and does not contain any other elements or compounds. In its pure form, it has a consistent composition and specific properties, such as conductivity and malleability. However, copper can be found in various alloys or compounds, which would not be classified as pure substances.
Copper is a pure substance.
Yes, copper is an element, which is a pure substance.
Copper wire is a pure substance, as it is made entirely of copper atoms.

Copper is a metallic element with the symbol Cu (29) and in its pure form contains only atoms of Copper. It is a pure substance. In addition, Copper is a soft metal and can be mixed with other metals to create alloys.
Yes, copper sulfate is considered a pure substance because it has a definite and uniform composition of copper, sulfur, and oxygen in a fixed ratio. It can be represented by a chemical formula (CuSO4) and is not a mixture of different substances.
No, it is a pure substance.
