Francium was discovered, see the link.
Francium was discovered by Marguerite Perey in 1939.
Gallium is from Gallia (the antique name of France).Francium is from France.
Radon (element #86) was discovered in 1900. Francium (#87) was discovered in 1939. Francium is the second rarest naturally occurring element. It is also one of the most reactive elements known to man and has a high isotopic instability, with a half life of about 22 minutes. Francium is a part of the Alkali metals group, which are all quite reactive with water and air, Francium being the most reactive. Francium will react explosively upon contact with air, and you wouldn't want to be there if it came into contact with water.
because it only has a half life of 22 minutes so by the time any one could get to it the francium had died
The chemical symbol of francium is Fr.
The element symbol of francium is Fr. It is a highly radioactive element with atomic number 87, making it one of the rarest naturally occurring elements on Earth.
Francium is a highly radioactive alkali metal element with the atomic number 87 and symbol Fr. It is the second rarest naturally occurring element in the Earth's crust and is extremely unstable, making it difficult to study. Francium was discovered in 1939 by Marguerite Perey.
The chemial symbol Fr is derived from the first two letters of the name Francium.
