All elements in the periodic table have chemical properties. Chemical properties are how they react with other elements to form compounds and new substances. This is very often determined by the movement of electrons and the size of the nucleus. A good example of this is the chemical behavior of the group 1 metals. The group 1 metals will want to lose one outer electron to fulfill a full outer shell so easily donate electrons meaning they are good oxidising agents but also have low first ionisation energies. This is different to the behavior of the halogens in group 17 where they have relatively high ionisation energies as they do not like to lose electrons but instead prefer to gain them meaning they have low electron affinities. All of these different behaviors with electrons and the radii and sizes are examples of chemical properties.
