Hafnium (Hf), with a mass number of 182 and an atomic number of 72, decays by beta emission. Here is a collection of fun and interesting facts about hafnium, as well as standard atomic data for the element. Some semiconductor fabrication processes use its oxide for integrated circuits at 45 nm and smaller feature lengths. There are five stable isotopes of hafnium, hafnium-176 to 180. And the atomic number is 72 - 2 = 70.

Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. An alpha particle contains 2 protons and 2 neutrons. Need an editable periodic table to edit? 178,49. As powdered hafnium can spontaneously ignite when exposed to air (pyrophoric). It is found in integrated circuits, vacuum tubes, and incandescent lamps. Isotopes of Hafnium. EC Number 231-166-4. So the mass number is 174 - 4 = 170. Check my Elements Comprehensive List. Relative atomic mass is also known as atomic weight (symbol: A r). Most of the isotope data on this site has been obtained from the National Nuclear Data Center.Please visit their site for more information.. Isotopes With A … The Element Hafnium - Known Isotopes. Mass Number The sum of the number of protons and neutrons of an atomic nucleus. MDL number MFCD00011032. This is not to be confused with the relative percentage isotope abundances which totals 100% for all the naturally occurring isotopes. Hafnium is used in nuclear reactors, mainly as nuclear control rods because hafnium is an exceptionally powerful neutron absorber.
