although once entirely made from copper, pure copper was too soft for most uses. People found out mixing chemicals with copper can strengthen it. The most familiar form of an alloy of copper are bronze and brass. Copper pennies are now just zinc coated with copper.

Copper and oxygen multivalent metal ions ionic compounds?

Copper and oxygen can form various multivalent metal ions in ionic compounds. For example, copper(I) oxide (Cu₂O) and copper(II) oxide (CuO) are ionic compounds where copper exists in different oxidation states. These compounds are formed by the reaction of copper ions with oxygen ions to achieve stability through the transfer of electrons.

Why are compounds of zinc white but compounds of copper have color?

Compounds of zinc are white because zinc atoms do not absorb visible light in the same way that copper atoms do. Copper compounds have color because copper atoms absorb certain wavelengths of visible light, leading to the perception of color in the compound. This difference in electronic structure is responsible for the variation in color between compounds of zinc and copper.
