What is RUTHERFORDIUM?
Summary
TLDRRutherfordium, symbol RF with atomic number 104, is a synthetic, radioactive element not found in nature. Named after Ernest Rutherford, it's created in labs and belongs to the d-block, group 4, and period 7 in the periodic table. Its most stable isotope, 267RF, has a half-life of 1.3 hours. Rutherfordium's chemistry is akin to hafnium, with some suggesting unique properties due to relativistic effects. A naming dispute between Soviet and American scientists was resolved in 1997 by IUPAC, establishing 'rutherfordium' as the official name.

Outlines
🔬 Rutherfordium: A Synthetic Element
Rutherfordium, symbol RF with an atomic number of 104, is a synthetic chemical element named in honor of physicist Ernest Rutherford. As a synthetic element, it does not occur naturally and can only be synthesized in a laboratory setting. Rutherfordium is radioactive, with its most stable known isotope, 267RF, having a half-life of about 1.3 hours. In the periodic table, it is positioned as a d-block element and the second of the fourth row transition elements, belonging to the seventh period and group four elements. Chemical experiments have shown that rutherfordium behaves similarly to hafnium, its heavier homologue in group four. Although some theoretical calculations suggest that relativistic effects might lead to significantly different properties, the chemical properties of rutherfordium are largely consistent with those of other group four elements. The discovery of rutherfordium in the 1960s was a point of contention between Soviet and American scientists, with the Joint Institute for Nuclear Research in the former Soviet Union and Lawrence Berkeley National Laboratory in California both claiming priority. It wasn't until 1997 that the International Union of Pure and Applied Chemistry resolved the dispute and officially named the element rutherfordium.
