Explain why there is an increase in reactivity as you go down group 2 |
Electron sheilding, atomic radius increases which causes nuclear charge to increase but is outweighed by increase in atomic radius and electron sheilding. Outer electrons are less attracted, easier to remove and thus more reactive. |
