    The elements are ranked (from most reactive to least reactive) in the following order: F, Cl, Br, I.

    The trends of reactivity for the periodic table follow a general pattern for metal and non-metal elements.

    For metals, reactivity increases moving down a group (column) and moving to the left within a period (row) on the periodic table.

    In this question the reactivity of a non-metal group (the halogens) is considered. For non-metals, reactivity increases moving up a group and to the right within a period. Note that the noble gases (located at the far right of the periodic table) do not follow this general rule as they are not more reactive than the halogens.

    By examining the periodic table, we see that the most reactive halogen should be at the top of the group, with each subsequent element having a decrease in reactivity. Therefore the order, in terms of most reactive to least reactive, is F, I, Cl and Br.

    The link below outlines the general trends in reactivity and provides some additional reading if desired.
