Explanation:

Trend in metallic property:

• As we move along a period from left to right, the metallic character decreases. The elements which are at the extreme left of the periodic table are most metallic in nature and the elements at the right side of the periodic table are non-metals in nature.
• As we go down the group, the metallic character increases and the non-metallic character decreases.
• So, metals at the extreme left and bottom of the periodic table are most metallic in nature.

Reactivity:

• As the metallic character increases, the Ionisation potential decreases and the reactivity of the elements also increases.
• The most reactive metal is thus Cs (Cesium), situated at the bottom left corner of the periodic table.

​

Hence, the most active metal known is Cesium.

• Francium is the element present at the bottom of the periodic table, but it is a lab-made element, and not naturally occurring, which makes Cs as the most reactive element.
