Francium exist in uranium and thorium ores; the chemical form is not known.
It is estimated that only approx. 30 g francium exist on the Earth.
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 is found in thorium and uranium ores in the earth's crust obtained by the decay of actinium
No it is not a drug, it is just a extremely rare source which is found near the crust of the earth :)
Francium was found by Marguerite Derey of the Curie Institute of France in 1939.
Francium doesn't exist in air.
Yes. Earth's crust is estimated to contain about 30 grams of Francium at any given time.
Francium is a highly radioactive and unstable element that is never found in its pure form in nature. If it were to be touched, it would likely react explosively with water or air. Due to its extreme rarity and radioactivity, no one has ever touched or felt francium.
The existence of francium in cosmos was not proved.
Francium is a member of the alkali metals family.
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
Natural francium exist in uranium and thorium ores.Artificial francium is obtained in particle accelerators.
