Yes. Earth's crust is estimated to contain about 30 grams of Francium at any given time.
It is estimated that only approx. 30 g francium exist on the Earth.
The existence of francium in cosmos was not proved.
- francium is extremely radioactive- the total quantity of francium on the Earth is approx. 30 g- the chemical and physical properties of francium are only estimated, not measured
It is estimated that the Earth crust contain approx. 30 g francium.
Francium exist in uranium and thorium ores; the chemical form is not known.
Natural francium is very scarce - approx. 30 g in the Earth crust.
3 grams of francium can destroy earth i know for definate it has been tested by several government and military scientists and that was concluded as long as you know how you can destroy earth with 3 grams of the francium
It is estimated that there are around 340 grams of francium in the Earth's crust at any given time. Francium is a highly unstable and rare element, with a half-life of only about 22 minutes, making it very hard to find in nature.
francium is found in thorium and uranium ores in the earth's crust obtained by the decay of actinium
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.
There is a very small amount of francium naturally occurring in the Earth's crust, estimated to be around 340-440 grams in total. Francium is a highly radioactive element with a very short half-life, making it extremely rare and difficult to study. It is typically produced in laboratories or nuclear reactors.
The total amount of the francium in the Earth crust is approx. 30 grams.
