What country was francium first discovered?
Francium was discovered by Marguerite Perey (from France) in 1939 during a study on actinium-227: she observed an energy level possibly attributable to a new element. After some chemical experiments she was sure that the radiation is from a new chemical element, after this called francium.
Why was francium not discovered?
Francium was discovered, see the link.
When was francium discovered and by whom?
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.
