In a laboratory.
It is a radio-active element, and will only be found in very specialist labs. dealing with radio-active materials.
The francium ion is found on Earth, but only in the most minute amounts, as to untraceable.
it is impossible to find fancium there is only a limited amount and that limited amount is very small you can only find this element in the core of the earth which is highly impossible to get to there is only 400g of frankium on earth at any one time
Francium exist in infinitesimal concentrations in uranium ores. Also francium is prepared by nuclear reactions.
Francium exist in infinitesimal concentrations in some uranium and thorium ores; the total quantity in the earth crust is estimated to be only approx. 30 g !
You can't; francium is so rare you can not even get a nanogram of it. Anyways, if you get it, it's so radioactively unstable it will just vaporize itself because of its own heat generated.
Francium exist in uranium and thorium ores.
Francium exist in uranium and thorium ores.
· Francium Sulfide (Fr2S) · Francium Phosphide (Fr3P) · Francium Bromide (FrBr) · Francium Sulfite (Fr2SO3) · Francium Hydrogen Oxalate (FrHC2­O4)
Francium is very reactive and unable to remain in elementary form - excepting absorption on gold foils.
Francium can form cations with the charge +1.
Francium is a true chemical element, not an example.
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.
Francium was found by Marguerite Derey of the Curie Institute of France in 1939.
Francium doesn't exist in air.
Francium is a member of the alkali metals family.
Natural francium exist in uranium and thorium ores.Artificial francium is obtained in particle accelerators.
Francium is not exclusively found in France, but rather, it is found throughout the Earth in extremely small quantities. Francium was discovered by a French scientist, Marguerite Perey.
Francium exist in uranium and thorium ores but it is not exploitable.
It was found in 1939.
francium is commonly found as hard rock unless it comes from gravestones
Francium exist in infinitesimal concentrations in uranium and thorium ores.
It is estimated that only approx. 30 g francium exist on the Earth.
In the nature francium exists only in infinitesimal amounts and because of this, it is considered generally an artificial element. Francium reacts with water.
Francium exist in uranium and thorium ores; the chemical form is not known.
