Radium is the most reactive in this group.
Radium
Sr
The most chemically reactive metals are the alkali metals. Francium is the most reactive of these and of all metal (although it is present on earth only in exceedingly small quantities, due to its radioactivity).The most reactive element available in useful quantities in Flourine.
fluorine is the most reactive non metal in the periodic table.
Francium is the most reactive metal because has the lowest electronegativity.

Fluorine is the most reactive non-metal.
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
Metals which can easily loose electron are most reactive. They are present in group-1.
The most explosive alkali earth metal on the planet is Francium. No actually Francium is still below Cesium. And Cesium is the second explosive on the planet. No one actually knows what the most explosive alkali metal is because they are not legally allowed to test it.
Francium (Fr) is the most reactive metal.
Lithium is the most reactive metal found.
silver
Cesium is the most chemically reactive metal.
fluorine is the most reactive non metal in the periodic table.
