Francium is a radioactive chemical element which is classified among the alkaline earth metals on the periodic table. It is extremely unstable, with a very short half life â approximately 20 minutes â and, as a result, it has few applications outside the realm of scientific research. The bulk of the world's francium is synthesized in labs; it only appears in nature in very small trace amounts, and it is an extremely rare element.
