How easy is it to cut francium?
Francium is extremely unstable. The most stable isotope of francium has a half-life of only about 22 minutes. Other isotopes of francium have half-lives measured in microseconds. Scientists predict there is less than one ounce of francium in Earth's crust at any one time. Because of this instablilty, it would be much easier to go get a cup of coffee and wait for francium to cut itself apart.
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.
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
Is sodium more active than francium?
Francium is more reactive than sodium.
Is potassium more reactive than francium?
Francium is more reactive than potassium.
Is francium harder than sodium?
The hardness of francium is not known.
Is francium harder or softer than sodium?
The hardness of francium is not known.
What is thephysical description of the element francium?
The standard state of Francium is a solid. Its color is not determinable because scientists estimate that there is no more than one ounce of francium in the earth's crust at one time. It is highly radioactive, and in order for scientists to even study it, they must create it.
Francium is a rare radioactive alkali metal at the bottom of group 1 Its properties have not been studied carefully Would you predict that francium would combine with water more or less readily than?
It is supposed that francium react with water more easy than any other element.
Is francium more or less reactive than cesium?
Francium is considered to be more reactive than caesium.
Is their a more reactive metal than francium?
Francium is considered as the most reactive metal; francium has the greatest electropositivity and the lowest electronegativity.
Nothing is as effective as stating the obvious but with less than one ounce of this helogen existing on the earth?
Francium. Oh, and you spell it Halogen :)
