Atoms can be shown with shells around the nucleus to represent the paths of the electrons "Whizzing" around the nucleus.
SHELL 1 - Fits TWO Electrons in this ring
SHELL 2 - Fits EIGHT Electrons in this ring
SHELL 3 - Fits EIGHT Electrons in this ring
SHELL 4 - Fits the REST of the electrons in here.
If the elements gain full shells then they become CHEMICALLY STABLE
ALL chemicals are reactive as the atoms are attempting to gain or lose electrons in order to obtain full shells, where they will therefore become chemically stable.
FULL SHELLS = CHEMICAL STABILITY OF ELECTRONS
