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.
What else can I help you with?
What is the physical state and appearance of francium?
Francium is a highly radioactive and rare alkali metal. It is a solid at room temperature, but due to its extreme radioactivity, it is typically stored in mineral oil to prevent reaction with moisture in the air. Francium also has a silvery-white appearance when freshly cut.
How was francium named francium?
Francium was named after France, the country it was dicovered in.
What is the numerical value of francium?
The atomic number of francium is 87.
What is the chemical formula for the compound Francium Bromide?
The chemical formula for Francium Bromide is FrBr (one francium atom bonded to one bromide atom). Francium is a highly reactive alkali metal and bromide is a halogen.
Is francium harder than sodium?
Francium is softer than sodium. Francium is a highly reactive metal that is classified as the most electronegative element on the periodic table. Sodium is also a soft metal, but it is harder than francium.
What elements do francium react with more?
The chemistry of francium is not known; it is probable that francium easy react with nonmetals.
What is the physical state and appearance of francium?
Francium is a highly radioactive and rare alkali metal. It is a solid at room temperature, but due to its extreme radioactivity, it is typically stored in mineral oil to prevent reaction with moisture in the air. Francium also has a silvery-white appearance when freshly cut.
Is an element that is soft and easy to cut cleanly with a knife likely to be a metal or a non metal?
The Alkali Metals. Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
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 combustible?
Not known today but probably francium don't burn.
Why francium iodide don't exist?
Francium iodide was not prepared but this compound should be real.Francium is very difficult to be prepared, unstable and because of the heat of decay is easy autovaporized - any experiment is possible.
What is a use of francium oxide and What is a compound of francium Is a compound francium oxide?
Francium has not applications and the oxide cannot be prepared.
Is copper easy to cut?
Yes, copper is easy to cut because it isn't tough.
Is francium a metalliod?
Francium is a metal.
How was francium named francium?
Francium was named after France, the country it was dicovered in.
What are chemical properties of francium?
The chemistry of francium is not known; francium has properties similar to caesium.
Why is the density of francium unknown?
We haven't sufficient francium for a measurement; also francium is autovaporized.
