Metallic character increases form right to left across a period on the periodic table, and from top to bottom down a group. The alkali metals in group 1 are the most active metals, and cesium is the last element in the group for which we have experimental data.

Francium is extremely rare and is radioactive, with the longest half-life at 22 min, so there is no empirical evidence that francium is the most metallic element.
