Energy required for a reaction can vary. Depending on the atom it changes.
The element will be more reactive if it has a low 1st ionization energy since it requires less Energy (https://gratisafhalen.be) to react. The most reactive element in Francium since it has the lowest 1st ionization energy level. If an element has a high electro-negativity then it will also be able to react with little energy.
