The valence shell is the outer shell of the atom. Some materials have a free electron in their valence shell and this electron can easily move from atom to atom. The free electrons are responsible for electrical current.
The electrons on the outermost energy level of the atom are called valence electrons. The valence electrons are involved in bonding one atom to another.

As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which âshareâ the electrons.
