What is RUTHERFORDIUM?

Summary

Rutherfordium, 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.
