Why are there no francium or rubidium batteries made?

Lithium is used to prepare batteries only because the oxidation potential of lithium is high but as we move down the group (Alkali metals) the ionization energy decreases because of shielding effect as well as size of atom increases thus the batte... read more

Francium-223 also has a shorter half-life than the longest-lived isotope of each synthetic element up to and including element 105, dubnium. Francium is an alkali metal whose chemical properties mostly resemble those of caesium. A heavy element with a single valence electron, it has the highest equivalent weight of any element. read more
