No, not at all. Fr is only artificially made as unstable isotopes with half-life times 4.8 and 21 minutes (Fr-221 and Fr-223 respectively)

Is francium not abundant because of the damage it causes?
Francium is very unstable and easily disappear.
Where is the most abundant location for the element francium?
Natural francium exist in uranium and thorium ores.
What is the least abundant of the eight rock-forming elements that make up most of the continental crust?
The 3 least abundant elements are Francium (Fr), Astatine (At),and Plutonium (Pu). Francium and Astatine come from the decay of Thorium (Th) and Uranium (U), are much more abundant. At any one time in the entire earth's crust there is only 30 grams of Francium and 25 grams of Astatine. Plutonium is only found in Uranium minerals. The amount of Plutonium is microscopic. Here are the 3 least abundant elements. Lowest 3. 89. Francium 90. Astatine 91. Plutonium
What is francium's most abundant isotope?
Francium has no stable isotopes. That means it doesn't really have a "most abundant" isotope; they're all pretty much nonexistent. There are trace amounts of 223Fr in uranium minerals, because it's a decay product of 227Ac (which is itself a decay product in the decay chain of uranium).
Is francium found in earth?
It is estimated that only approx. 30 g francium exist on the Earth.
Is francium in earth?
Yes. Earth's crust is estimated to contain about 30 grams of Francium at any given time.
Where can you find francium other than on earth?
The existence of francium in cosmos was not proved.
Can francium destroy earth?
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
What is the viscosity of francium?
The Earth crust contain approx. 30 g francium.
How many grams of francium exist in the earth's crust at any one time?
As francium is the rarest type of atoms in the world, there is approximately only 20 francium atoms left on Earth.
How much francium is there?
Francium is so rare its unable to be bought
What are two interesting properties of francium?
- 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
