Is gold bigger than copper

Gold and copper can vary in size depending on the context in which they are measured. However, if you're referring to their density and atomic structure, gold is denser and heavier than copper, meaning that for the same volume, gold will weigh more. In terms of elemental abundance in the Earth's crust, copper is more prevalent than gold. Thus, while gold is not "bigger" in a physical sense, it is more dense than copper.
