State its molecular formula, please.
Note: This is not a homework question, i'm just a curious person!

Fluorine (F). It has the greatest electronegativity. In consequence, it is extremely difficult to isolate and rarely occurs as a free element.

When we consider the reactivity of elements we should consider their electronegativity which is a measure of attracting power when bonded.on the electronegativity scale fluorine has the highest electronegative power.the molecular formula is fluorine molecule(F 2)

Europium (Eu)--Europium ignites in air at about 150 to 180°C. Europium is about as hard as lead and is quite ductile. It is the most reactive of the rare earth metals, quickly oxidising in air. It resembles calcium in its reaction with water. It is used in television screens to produce a red colour.

in water i'd say Rb or Fr. Fl is highly electronegative and fairly reactive as well. just depends on conditions
