Found by Marguerite Perey in France in 1939, francium has an atomic variety of 87.
It is the heaviest of the identified alkali metals. It has the very best equal weight of any factor. The chemical properties of Francium are much like Cesium.
There are 33 accepted isotopes of Francium, and all of them are extremely unstable. Due to this fact, details about the chemical parts of Francium is obtained by radioactive strategies.
Pure Francium is the results of actinium alpha degradation. It happens naturally in uranium minerals. If Thorium is bombarded with protons, synthetic Francium could be obtained.
