Best Answer

The reactivity of francium with water would be more reactive than most of the other alkali metals, because the lower down the column of alkali metals you go in the Periodic Table the more reactive the element becomes in cold water. Therefore, if francium was to react with cold water it would react by giving off an explosion.

Francium is an Alkali metal, i.e., it belongs to Group I-A. Also, it is the bottom-most element in that group and the chemical reactivity increases as we down in Group I-A. So, Francium is chemically most reactive element. Also, all alkali metals react vigorously with water. So, Francium is very reactive with water...

What is the explosive force of Francium when it comes in contact with cold water?

Francium is so unstable enough cannot be synthesised and stored long enough to react with water, but assuming that the trend down the group continues it will be even more explosive that Cesium

What metals can react explosively with cold water?

Rubidium, caesium and francium. Potassium will generate enough heat to ignite the hydrogen produced in the reaction but the reaction is not really explosive.

Which fruit freezes the best out of strawberry banana and apple?

The strawberry will freeze the best because it has more oxygen it a has water that will get cold and freeze. This is why it is the answer. Scientists have studied this and they predict that the seeds and water that are in the strawberry give of more oxygen that they freeze up when it gets somewhere cold.
