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.

Can francium destroy earth?
No, francium cannot destroy Earth. It is a highly reactive alkali metal that could potentially cause damage if not handled properly, but it does not possess the capability to destroy the entire planet.
What is the atomic number of francium?
The atomic number of francium (Fr) is 87.The atomic weight of Fr is 223 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
This element is found in the earth crust no more than 30 grams?
The element with an atomic number higher than 83, bismuth, is the element which occurs the least in the Earth's crust, with an average abundance of around 0.2 parts per million, or less than 30 grams per ton of rock.
Which element Is an alkali metal with a mass greater than 200?
Francium is an alkali metal with a mass greater than 200 atomic mass units. It is the heaviest alkali metal and is highly radioactive, with a very short half-life.
What is concentrated containing 5 grams of salt in 10 grams of water 18 grams of salt in 90 grams soft water?
A solution containing 5 g sodium chloride in 10 g water doesn't exist.
Is francium in earth?
Yes. Earth's crust is estimated to contain about 30 grams of Francium at any given time.
Why did it take the scientists nearly 80 years to discover francium?
The total amount of the francium in the Earth crust is approx. 30 grams.
Why did it take scientists nealy another 80 years to discover francium?
The total amount of the francium in the Earth crust is approx. 30 grams.
Hy did it take scientists nearly anther 80 years to discover francium?
The total amount of the francium in the Earth crust is approx. 30 grams.
Why did it take scientists nearly another eighty years more to discover francium?
The total amount of the francium in the Earth crust is approx. 30 grams.
Why did it take 80 years longer to descover francium the all the other alkali metals?
The total amount of the francium in the Earth crust is approx. 30 grams.
Why did it take scientists nearly another 80 years to discover francium as simple as possible?
The total amount of the francium in the Earth crust is approx. 30 grams.
Why is francium less cared in chemistry?
Francium is often ignored because it is the second rarest element on the planet. Only about 30 grams of it exist in Earth's crust at any given time. Nobody has been able to have more than a few thousand francium atoms in one place. Francium is also has a very short half-life, 22 minutes. Meaning that if you have a sample of francium half of it will have decayed into other elements after 22 minutes.
What element has no more the 30 grams in Earth's crust at any one time?
30 grams of Astatine can be found in the earths crust at any one time.
How much francium is there is the world?
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
Why did it take another 80 years to discover francium after all the other alkali metals?
Francium is a very unstable element it is estimated that only about 30 grams exist in the earth's crust. Scientists knew that an element like Francium should exist but had yet to find it. It was found in very small amount in uranium ore (only a few atoms) noticed by it's distinct radiation as the most stable isotope has a half-life of on 22 minutes.
How much francium is there?
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.
