The periodic trend of reactivity depends on whether the elements are metals or nonmetals.
For metals, reactivity increases down a group and from right to left across a period.
Nonmetals do the opposite. For nonmetals, reactivity increases up a group and from left to right across a period.
Francium is the most reactive metal, and fluorine is the most reactive nonmetal.
