WebChemical reactions release or absorb energy. Activation energy is the amount of energy that needs to be absorbed to start a chemical reaction. Exothermic reactions release more energy than they absorb. Reactants have higher bond energies than products. Excess energy is released by the reaction. WebChemical Reactions. Close examination of the periodic table will show that the atoms of all of the elements in the last column of the table (i.e., helium, neon, argon, etc.) have eight electrons in their outer shells (with the exception of helium). Therefore, their outer electron shells are full. These elements are known as the noble gases ...
