    How copper conducts Copper is a metal made up of copper atoms closely packed together. If we could look closely enough we would see that there are electrons moving about between the copper atoms. Each copper atom has lost one electron and become a positive ion. So copper is a lattice of positive copper ions with free electrons moving between them.
