Generally speaking electrons are found in shells which we also call principal energy levels located at increasing distances from the central nucleus the first ionization energy or ie with little sub 1 of an atom of an element describes the amount of energy required to remove the outermost electron from an atom of

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst
