What is the density of francium in 20 degrees Celsius?
The density of francium is supposed to be 1,72 g/cm3.
What is the only element that has not been isolated from the earth's crust?
Technetium is the only element that has not been found in nature but has been produced synthetically.
What is the most electropositive element?
Cesium is the most electropositive stable element. Francium is more electropositive (at least in theory) but only about 30 grams exists on the entire planet as it is highly radioactive so no one has been able to check.cesium is most electropositive element in periodic table.Ceasium
Has a Francium bomb ever been made?
No, francium bombs have never been made. Francium is a highly radioactive and rare element that is not readily available in large enough quantities to create a bomb. Additionally, the extreme reactivity and short half-life of francium would make it challenging to use in a practical weapon.
Is francium related to water or caesium?
Francium is an alkali metal, similar to caesium. Water (H2O) is a compound,not an element. Francium, although it is believed to have never been tested, is thought to have been the most reactive element with water. It is among the alkali metals in group 1 on the periodic table of elements.
What are some things that contains francium?
Francium is a highly reactive and radioactive metal that is very rare in nature. It is found in minute quantities in uranium and thorium ores. It has also been produced in laboratories through nuclear reactions.
Does francium have an odor?
Francium is a highly radioactive and unstable element that is extremely rare in nature. Due to its radioactivity and short half-life, francium is difficult to study and therefore its odor has not been specifically identified.
All alkali metals except francium had been disconerd by 1860 why did it take scientists another 80 years to find francium?
Francium is the second rarest element on earth so that's probably why it took a little longer to discover.
Which element has the largest size of atoms?
Atomic radii have not been measured or calculated based on theoretical principles for all of the elements. However, based on the information available in the wikipedia tables of atomic radii it would appear that the largest atom will prove to be that of francium.
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!
What is the history of the element of the element cobalt?
cobalt has been used since ancient times but was first isolated by Georg Brant in 1735.
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.
