in the alpha decay of francium-221 what daughter element is produced
Francium Francium-221 has a half-life of 4.8 minutes.[5] It is the ninth product of the neptunium decay series as a daughter isotope of actinium-225.[19] Francium-221 then decays into astatine-217 by alpha decay (6.457 MeV decay energy).[5]
