Which is the most reactive metal: Caesium or Francium? [duplicate]
We do not really know. Francium is known only as highly radioactive, short-lived isotopes and we have very little experimentally based chemical information about it. Most of its properties are mere predictions.

Caesium is more reactive. Generally as you go down the periodic table, electro-positivity increases. However, for the really heavy elements, the presence of so many positively charged protons in the nucleus has the affect of causing the electrons to move round at incredibly fast speeds approaching the speed of light. As Einstein realised at such speeds strange things begin to happen. The electrons become a little closer to the nucleus than expected and they also become slightly harder to remove than expected.

The reactivity series consists of elements whose properties are FULLY known and understood. It is on the basis of whether an element can displace another from its salt solution (this is what you've been told at grade 10 Indian schooling level I guess?).
Francium, on the other hand is a radioactive element, with a half life of only 22 minutes for its most stable isotope
(Francium-223). Therefore, we can only make predictions, and not observations, about the nature of its salts and whether they would displace other elements from their salt solution or not.
