Coprecipitation experiments performed in 2021 studied rutherfordium's behaviour in basic solution containing ammonia or sodium hydroxide, using zirconium, hafnium, and thorium as comparisons. It was found that rutherfordium does not strongly coordinate with ammonia and instead coprecipitates out as a hydroxide, which is probably Rf(OH) 4. [84]

Despite these unsuccessful attempts to observe long-lived superheavy nuclei, [34] new superheavy elements were synthesized every few years in laboratories through light-ion bombardment and cold fusion [k] reactions; rutherfordium, the first transactinide, was discovered in 1969, and copernicium, eight protons closer to the island of stability ...
When IUPAC made the final decision of the naming of the elements beyond 100 in 1997, it decided to keep the name "lawrencium" and symbol "Lr" for element 103 as it had been in use for a long time by that point. The name "rutherfordium" was assigned to the following element 104, which the Berkeley team had proposed it for. [43]
The last element of the group, rutherfordium, does not occur naturally and had to be made by synthesis. The first reported detection was by a team at the Joint Institute for Nuclear Research (JINR), which in 1964 claimed to have produced the new element by bombarding a plutonium -242 target with neon -22 ions, although this was later put into ...
1920s: The Spanish Flu. In the fall of 1918, a mutated version of the virus that claimed its first victims in the spring made its way around the world, causing the death rate to escalate quickly ...
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 ...
