Francium is probably the rarest element found in the Earth's crust. As Francium is so rare and the isotopes are so short-lived, we don't know too much about the element. So experts think that there is no more than 15 grams in the Earth's crust.
I hope I answered your question right
It is estimated that the Earth crust contain approx. 30 g francium.
Francium is not a commercial product.
The chemistry of francium is practically unknown.
Francium is not a commercial product and hasn't practical applications today.
Francium is not typically bought or sold due to its extreme rarity and radioactivity. It is created in very small quantities in laboratories for research purposes. Therefore, there is no standard market price for francium.
The cost of francium is not applicable as it is extremely rare and unstable, making its commercial use and availability nearly non-existent. Francium is primarily used for research purposes due to its radioactivity and scarcity.
Francium isn't available for several reasons:It is highly radioactiveIt will react extremely violently with air and waterIt is highly toxicIt is very rare (about 21 grams exist in the entire world)There is no dealer/seller who can or will sell you Francium, whatever they say about it.
The metal francium has a much lower melting point than platinum has.
Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
Francium is extremely unstable. The most stable isotope of francium has a half-life of only about 22 minutes. Other isotopes of francium have half-lives measured in microseconds. Scientists predict there is less than one ounce of francium in Earth's crust at any one time. Because of this instablilty, it would be much easier to go get a cup of coffee and wait for francium to cut itself apart.
Francium is a metal.
