The alkalai metals and the halogens. The reason is that the alkalai metals only need to lose one electron and drop that energy level to achieve a full valence (outermost) energy level. Conversely the halogens only need to gain one electron to achieve a full valence energy level.
Stability is achieved when the valence energy level is full. Since both these families are closest to that state, they are most likely to spontaneously react!

Every element is trying to get to its most stable electronic configuration. So the families of elements that are most reactive are the ones that are closest to reaching stability, either by losing an extra electron or gaining the last one they need…
Hope that helps.
