Because it has only one valence electron, rubidium is very reactive, especially with water. It has 37 electrons which tells you that it has quite a lot of energy. So, if it contacts water the reaction would be very energetic. The H2O molecules are broken apart and the rubidium bonds with the oxygen. The heat released during this exothermic reaction will ignite the hydrogen that was released from the water.
Boom!

Caesium will more than tarnish. It will spontaneous catch fire on contact with air.
Caesium is an extremely reactive chemical element.
Cesium and francium are not commonly found in school environments due to their high reactivity with air and water. They are highly dangerous elements that require special handling and storage procedures that most schools are not equipped to accommodate. Subsequently, their use in school laboratories is restricted to ensure student safety.
Caesium was discovered in 1860.
Caesium is a solid metal.

I suppose that francium cannot be stored: the half life is short.
