The name francium is derived from France.
Francium is a chemical element, its atomic number is 87 and its symbol is Fr. It's a metal that is highly radioactive. It was discovered by French scientist Marguerite Perey in the year 1939. Perey worked at the Curie Institute in Paris, France, she first named the new element 'Actinium-K', later she proposed the name 'Catium', but after finding opposition to it, she proposed the name 'Francium', after France, the name was accepted in the year 1949 by the International Union of Pure and Applied Chemistry.
Francium is a naturally occurring radioactive element that is produced as a decay product of uranium and thorium. It is found in tiny amounts in uranium and thorium ores. Francium was first discovered in 1939 by Marguerite Perey in France.
The chemical symbol Fr is derived of course from francium - the first two letters; it is a rule in the system of naming chemical elements.
The least electronegative element is francium, which has a Pauling electronegativity value of 0.7. Francium is a highly reactive metal and is rare in nature.
The first 7s electron appears in francium (element 87) on the periodic table.
Francium is the Latin name of this element.
