What is the second most reactive metal?
The 2nd most reactive is Cesium after Francium. If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.
What are the three weak alkali?
Lithium, Sodium and Potassium are the 'weaker' alkali metals. Rubidium, Caesium and Francium are the most volatile. Francium is only found in micron-grams and is highly radioactive.
What is the difference between rubidium and seslium?
If you mean "What is the difference between rubidium and cesium?" then Rubidium and cesium are two different elements.They have similar properties but cesium is denser and has a higher atomic mass.Cesium also reacts more vigorously with water and air.
Is rubidium in any household objects?
No, rubidium is not found in household objects.

Does rubidium cesium and francium have the same atomic radius?
The empirical atomic radius of rubidium is 235 pm.The empirical atomic radius of caesium is 260 pm.The empirical atomic radius of francium is supposed to be approx. 260 pm.
How do you predict that francium would react?
The chemical reactions of francium are probably similar to the reactions of caesium or rubidium.
