formation of chemical bonds? Valence electrons are the electrons that are on the outermost shell of the atom’s electrons which are can be either given away‚ added‚ or to be shared. When these electrons are given away‚ added to or shared‚ there is a chemical change occurring and the compound that is formed is changed from the original elements. This is called bonding which is pretty much the realm of the electrons. It is the sharing of electrons from each atom that define the chemical bond. Because
