Francium was discovered in 1939 by the Frenchwoman Marguerite Perey, who established the presence of a 21-minute radio-isotope with properties of an heavy alkali element among the decay products of actinium. Mlle. Perey also isolated this product, determined its radio-chemical and nuclear properties, and showed that actinium is a product of radioactive decay. The initial proposed name was "actinium K", following the naming system for natural radioactive sources. Later, she proposed the name francium in honor of her country - France. With the exception of some transuranians, francium is the most unstable element known. Its chemistry is not well known but we can say that it is similar to the other heavier elements of the family such as rubidium and cesium.
 * History of Francuim**

The element Franceium was named after the country of France.Francium was discovered by Marguerite Catherine Perey, a French chemist, in 1939 while analyzing actinium's decay sequence. Although considered a natural element, scientists estimate that there is no more than one ounce of francium in the earth's crust at one time. Since there is so little naturally occurring francium on earth, scientists must produce francium in order to study it. Francium can be produced by bombarding thorium with protons or by bombarding radium with neutrons.

Health effects of francium
As it is so unstable, any amount formed would decompose to other elements so quickly that there’s no reason to study its effects on human health.

** Environmental effects of francium **
Due to its extremely short half-life, there’s no reason for considering the effects of francium in the environment.
