Both Group 1 and Group 7 are very reactive, this is because they have only one atom in their otuer energy shell to lose/gain to achieve stable electronic structure.
Group 1 elements become more reactive further down the periodic table as elements increase in size therefore they have more occupied electron shells which ar e further away from the nucleus and so the force is much weaker and the easier the electron is lost. However, Group 7 elements become less reactive further down the periodic table s for the same reason as the group 1 elemtns (bigger atoms, more electrons, further distance from the nucleus, weak forces) but it instead becomes harder to GAIN an electron and so they are less reactive.
