How do I figure out the reactivity of certain elements to know which ones are more reactive than others?

Thanks

      Hi Igaune :)

      The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.

      Bye :D
