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 can be obtained by the following nuclear reaction: 197Au + 18O = 210Fr + 5 n
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
1. Francium exist naturally, but in infinitesimally concentrations, in uranium ores. 2. Francium can be obtained also artificially, by nuclear reactions.
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.
