What happens to the reactivity of Group 1 elements going down the group and describe why that trend occurs?
The reactivity of Group 1 elements increases down the groupAs the atom becomes larger so the attraction between the positive nucleus and negative electron becomes weaker. Shielding also increases meaning that the number of atomic energy levels increases. This means that less energy is required to remove the single electron from the outer shell so more reactive.
