It depends on the placing of the element in the Periodic Table. For the far left, group 1, the most reactive element is the one closest to the bottom. For the far right, the most reactive is the one closest to the top.
The table follows certain trends, depending on it's placement in the periodic table. By learning these trends, you'll be able to tell at a glance. For example, Francium, the bottom-left most element only ever exists for a fraction of a second; it's so reactive, it reacts when it is created.
