The experiments relied on the expectation that rutherfordium would be a 6d element in group 4 and should therefore form a volatile molecular tetrachloride, that would be tetrahedral in shape. [72] [79] [80] Rutherfordium(IV) chloride is more volatile than its lighter homologue hafnium(IV) chloride (HfCl 4) because its bonds are more covalent. [2]

However, the last step in this chain was uncertain. After observing the five alpha decay events that generate dubnium-268, spontaneous fission events were observed with a long half-life. It is unclear whether these events were due to direct spontaneous fission of 268 Db, or 268 Db produced electron capture events with long half-lives to ...
