Metals which can easily loose electron are most reactive. They are present in group-1.
Most reactive metal is Sodium.Reacts vigorously with water.Lithium is also one of the most reactive metal.
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
Francium (Fr) is the most reactive metal.
Lithium is the most reactive metal found.
Cesium is the most chemically reactive metal.
Francium is the most reactive metal because has the lowest electronegativity.
fluorine is the most reactive non metal in the periodic table.
Radium is the most reactive in this group.
Potassium is not the most reactive, Francium is.
Aluminum is pretty reactive, but it is nowhere near the most reactive.
Francium is the most reactive metal and fluorine the most reactive nonmetal.
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.
