Copper and other metals are good conductors of electricity,
give reasons.
Answers
Answer:
Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions. The electrons then move freely throughout the electron sea.
So copper is a lattice of positive copper ions with free electrons moving between them. ... The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity.

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. (The electrons are a bit like the particles of a gas that is free to move within the surfaces of the wire).
The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity.
