Francium Water Test

From what scientists know franciums reaction when put in water should be greater than all the other alkali metals if hypothetically one were to obtain a gram or two of francium and react it with water the reaction would probably be very quick as it indeed is the most reactive alkali metal a fresh francium surface would soon tarnish because of reaction with oxygen and moisture from the air. There are thought to be only 30 grams of it on the earth at one time.

Francium is very scarce and expensive.

Francium water test. Franciums most stable isotope francium 223 has a half life of about 22 minutes. 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. Firstly francium is really rare.

Francium is an alkali metal whose chemical properties mostly resemble those of caesium. Francium is below cesium on the table and would react more readily and violently. It was discovered in france in 1939 by a french physicist called marguerite perey.

It is part of the alkali metals group which all react with water. Francium number 87 was the last of these elements to be discovered in nature. It decays into radium 223 through beta decay or into astatine 219 through alpha decay.

This occurs because each of the alkali metals is characterized by having a single valence electron. Francium 223 also has a shorter half life than the longest lived isotope of each synthetic element up to and including element 105 dubnium. If francium ever touched water it would produce a very violent reaction in the form of an explosion.

This electron easily reacts with other atoms. 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. It is umlikely that anyone has ever reacted the metal with water.

A heavy element with a single valence electron it has the highest equivalent weight of any element. Cesium releases enough energy that even a small piece blows up in water. It decays into radium 223 through beta decay or into astatine 219 through alpha decay.

Francium fran see um is the most reactive metal and so quickest to react. It is radioactive and it breaks down into other elements very quickly.
