Answer 2

The IUPAC name of the element having atomic number 104 is Rutherfordium (Rf).

• Initially, elements with atomic numbers more than 100 are given common names.
• These common names are derived by the name of each number appearing in the atomic mass.
• hence an element with atomic number 104 has the common name Unnilquadium.
• The Joint Institute for Nuclear Research located in present-day Russia named the element 104 kurchatovium (Ku) after the father of the Soviet atomic bomb Igor Kurchatov.
• At the same time, the University of California, US, named it rutherfordium after Ernest Rutherford.
• In 1997, rutherfordium was accepted as the IUPAC name of element 104.
