Francium (Fr), an extremely rare radioactive element
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.
Francium (Fr) is the most reactive metal.
Lithium is the most reactive metal found.
Cesium is the most chemically reactive metal.
The elements in the group 17 are the most reactive non metals. In the group, the reactivity decreases downwards as the ionic radius increases. Therefore fluorine is the most reactive non metal.The halogens are the most reactive non metals. They are in the 17th group of the periodic table. Fluorine is the most reactive non metal.Chlorine is most reactive non metal.It is present in group-17. It forms bonds by gaining one electron.
fluorine is the most reactive non metal in the periodic table.
Francium is the most reactive metal because has the lowest electronegativity.
Potassium is not the most reactive, Francium is.
Radium is the most reactive in this group.
Aluminum is pretty reactive, but it is nowhere near the most reactive.
