Explain the trends in reactivity as you move down group one elements.

As you move down group one atomic radius increases. As a result the attraction to outer electrons is weaker. As there are an increased number of energy levels, shielding to the outer electrons also increases. Therefore the outer electrons are less tightly held, meaning they can be lost easier in reactions making the elements more reactive as you move down group one.
