It has slightly higher ionization energy than cesium.

Francium water solubility. 18860 mean or weighted mp vpmm hg25 deg c. 424e 009 modified grain method subcooled liquid vp. Francium is below cesium on the table and would react more readily and violently.

Francium number 87 was the last of these elements to be discovered in nature. Example the lithiumcalcium sodium potassiumrubidium francium all are alkali metals. Base which is soluble in water is called alkali.

From its position in the table it was clear that element 87 would be a reactive alkali metal the heaviest member of the family lithium sodium potassium rubidium and caesium. 2114e004 log kow used. During the cold war the un tried to secure the only 15 grams of francium on earth.

By the way its not. Like alkali metals it is readily oxidized in air and vigorously react with water. Rubidium ignites with a red flame.

Cesium releases enough energy that even a small piece blows up in water. It is the least electronegative element so it is chemically reactive alkali metal. Francium 223 also has a shorter half life than the longest lived isotope of each synthetic element up to and including element 105 dubnium.

It however didnt go as planned and led to the only francium water reaction in history. Francium is an alkali metal whose chemical properties mostly resemble those of caesium. Francium is very scarce and expensive.

Francium atom is an alkali metal atom. However given that all the other group 1 elements react to form colourless solutions of the hydroxide and hydrogen gas h 2 it would be strange were francium not to do the same. A radioactive alkali metal with the atomic symbol fr and atomic number 87.

They form sodium hydroxidepotassium hydroxidecalcium hydroxide all are strong bases when they dissolve in water they form strong alkali. A small amount of lithium will float on water and burn. And readily loses it outer shell to become nobel element.

A heavy element with a single valence electron it has the highest equivalent weight of any element. Potassium breaks apart burning with a violet flame. Sodium burns more readily.

Nearly all francium salts are water soluble. Log octanol water partition coef src.
