WebJul 9, 2024 · How does the reactivity of Group 1 metals change? As you go down a group the atomic number increases. The number of shells of electrons also increases. The electron shells between the outer electrons and the nucleus have a ‘shielding’ effect which reduces the attraction of the outer electrons to the nucleus. All alkali metals have one ...
