Density of Gold and Copper

Pure gold is one of the most dense elements on the Periodic Table.

The density of an object is a physical property that is usually given in mass per unit volume. For example, grams or cubic centimeter or pounds per gallon. This property determines whether an object floats or sinks in a liquid.

Density of Metals

The density of metals is temperature-dependant. This means that as a metal is heated or cooled, it's density decreases or increases accordingly. As heat is added, atoms in the metal become energized and spread out, thereby making the metal expand, causing the density to decrease. The opposite effect occurs when a metal is cooled.

Density of Gold

At ambient, or room temperature, the density of gold is 19.32 grams per cubic centimeter. This means that one cubic centimeter of gold weighs 19.32 grams. For reference, a cubic centimeter is about the same size as a jelly bean.

Density of Copper

The density of copper is 8.92 grams per cubic centimeter--much less than gold.
