First shell = 2 electrons
second shell+ = 4 electrons - 3Nucleus = protons (positive) and neutrons (neutral)Law of Conservation of Mass
------------------------
No atoms can be created or destroyed
in a chemical reaction
the total mass of reactants = total mass of products - 4(s) = solid form (l) = liquid form (g) = gas (aq) = aqueous solution
