Best Answer: Generally, the elements become more reactive as you move down and to the left (in a diagonal line). As you move down, the outer electron shells are positioned further away from the positive nucleus, with the electrostatic force holding the element together growing weaker (due to increased distance).
Caesium and fluorine. Group I metals are the most reactive metals as they only have one electron in their outer shell which is easy to lose; they get more reactive as you go down the periodic table as the electron is further from the nucleus and shielded by the inner electrons.
