The alkali metals all react with water. which is the most reactive metal?

kifflom [539]

Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be FRANCIUM, which is at the base of Group One.

Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.
