Explain the reactivity of group 1 metals
The reactivity of group 1 metals increases as you go down the group. This is due the number of electron shells increasing, leading to the distance between the outermost electron and the nucleus. The increased distance reduces the electrostatic attraction which means that it is easier to donate the electron, allowing an swifter reaction.
