Francium IS a stupid element. It has a half life of 22 minutes and barely exists at all, only naturally occurring as a product of the extremely rare alpha decay series ²³⁵U ➝ ²³¹Th ➝ ²³¹Pa (𝜷 decay) ➝ ²²⁷Ac ➝ ²²³Fr (1.38% chance). There’s less than a gram of it on earth at any given moment. It has no uses to anybody and it isn’t even the most reactive group 1A element due to relativistic effects fucking up its electron binding energies. Stupid substance.

If you somehow asked a genie to get you a gram of Francium in a sealed vial so you could do an experiment with it, the genie would just give it to you because the enormous amount of radioactivity it produces would instantly vaporize the sample and cook you alive. Absolute dogshit isotope and its synthetic siblings are just the same but worse
