Uses of Francium
Since francium is produced in tiny quantities in nature, it does show any much commercial applications.
- Francium has been used in the field of research, chemistry and also in the atomic structure.
- It is used for diagnostics for curing cancers.
- It is also used in many spectroscopic experiments.
- Francium is a highly radioactive metal, and since it exhibits a short half-life, it does not have more impact on the environment.
Properties of Francium
- Francium is a least founded metal on the planet earth and rarely found in nature. It is considered to be the second rarest metal discovered on the earth’s crust next to the Astatine.
- Francium is an element with chemical symbol Fr and atomic number 87 in the periodic table. It is produced both by naturally as well as by artificial methods.
- Most probably, it is assumed that about 340-550 gms of this metal francium are found in the earth’s crust.
- Francium occurs on the decay of the alpha particles, which are found in the minerals of uranium.
- This metal has about 34 isotopes that are said to be occurring in nature. Francium has the only 1-valence electron.
