Why do the atoms in a piece of copper metal have no net charge?

The charges of the positive and negative copper ions cancel each other out. When a copper atom loses electrons, it also loses a corresponding number of protons.The copper atoms exchange neutrons instead of electrons

Explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
