Natural francium exist in uranium and thorium ores.
Artificial francium is obtained in particle accelerators.
francium is found in thorium and uranium ores in the earth's crust obtained by the decay of actinium
Francium was first obtained by Marguerite Perey in 1939 from the radioactive decay process of actinium. It is a highly unstable and rare alkali metal that is found in trace amounts in uranium and thorium minerals.
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
If francium could be obtained in large quantities would have a definite volume.
Francium can be obtained by this reaction:Au-197 + O-18 = Fr-210 + 5 n
Francium can be obtained in a particle accelerator with this reaction:Au-197 + O-18 = Fr-210 = 5 n
Francium is obtained only by a nuclear reaction: 197Au + 18O = 210Fr + 5 n
Francium can be obtained in a particle accelerator with this reaction:Au-197 + O-18 = Fr-210 = 5 n
Francium was found by Marguerite Derey of the Curie Institute of France in 1939.
Francium doesn't exist in air.
Francium is a member of the alkali metals family.
