The difference between Gold and Mercury on the Periodic Table is one Proton. If I add one proton, solid Gold turns into a silvery liquid metal that's extremely toxic to humans. How can the addition of a single proton have such a profound effect on an element's properties?

if you add one protons, an electron will be added too (captured from the environment) and also the organisation of energy levels of electrons will be different. From this, it will change the properties of the atom.
