'''Francium''' is an [[element]]. It is very unstable and radioactive. It lasts very short. If it existed, it would be very reactive, more reactive than [[caesium]]. It is the heaviest [[alkali metal]]. It melts very easily.

'''Francium''' is an [[element]], it is the heaviest discovered [[Alkali metal]]. It is very unstable and radioactive. It lasts for a very short time period (half life of approximately 22 minutes<ref>http://www.chemicool.com/elements/francium.html#appear</ref>) before decaying into [[Astatine]] via alpha decay or [[Radium]] via Beta Decay.

It is estimated that only between 20 and 30 grams of it exist in the earth's crust at any given point in time <ref>http://www.webelements.com/francium/</ref> and is in fact the second rarest naturally occurring element after Astatine. The only reason it exists is because of its part in the decay chain of [[Uranium]].

Francium would presumably be more reactive than [[Cesium]], reacting violently with Water to produce Francium Hydroxide and Hydrogen Gas. It would also react with Oxygen rapidly in the air. It has an estimated melting point of 27 degrees Celsius, which would make it [[liquid]] in a warm room. None of these are confirmed owing to the rarity of the element and are based on the reactivity of the rest of the series.
