Thus, in potassium, the outermost electron is better shielded from the attractive force of the nucleus. It follows, therefore, that this outermost electron is more easily lost than it is in sodium, so potassium can be converted to ionic form more readily than sodium. Hence, potassium is more reactive than sodium.
