Rutherfordium Element in Periodic Table | Atomic Number Atomic Mass

Rutherfordium

Rutherfordium Element:

Rutherfordium is a synthetic chemical element and it is a member of group 4 and period 7 in the periodic table. The atomic number of rutherfordium is 104 and it is indicated by symbol is Rf. Rutherfordium is a kind of transuranium and radioactive element which cannot be found in nature and it  can only create in a laboratory. It doesn’t have any stable or naturally occurring isotopes.  267Rf is the most stable isotope; it has half-life of approximately 1.3 hours.

Uses of Rutherfordium:

  • Rutherfordium has been in very small quantities and the half-life periods of its isotopes are too short. Hence, the use of Rutherfordium is confined to scientific research only.
