Rutherfordium

Description

 

Rutherfordium is a radioactive synthetic element, named in honor of New Zealand physicist Ernest Rutherford. In the 1960s, small amounts of rutherfordium were produced in laboratories in the former Soviet Union and in California. The priority of the discovery and therefore the naming of the element was disputed between Soviet and American scientists, and it was not until 1997 that International Union of Pure and Applied Chemistry (IUPAC) established rutherfordium as the official name for the element.
