Iron has four naturally-occurring stable isotopes, 54 Fe, 56 Fe, 57 Fe and 58 Fe. The relative abundances of the Fe isotopes in nature are approximately 54 Fe (5.8%), 56 Fe (91.7%), 57 Fe (2.2%) and 58 Fe (0.3%). 60 Fe is an extinct radionuclide which had a long half-life (1.5 Myr). Much of the past work on measuring the isotopic …

WebAn isotope is a variation of an element where the atom contains the same number of protons and electrons, but differs in the number of neutrons it contains in the nucleus. For example this shows three isotopes of … WebIron-60 is radioactive and completely decays away within 15 million years, which means any iron-60 found on the earth must have been formed much later than the rest of the 4.6 …
WebIron is the fourth most abundant element, by mass, in the Earth’s crust. The core of the Earth is thought to be largely composed of iron with nickel and sulfur. The most common iron … WebMuch of the past work on isotopic composition of iron has focused on the nucleosynthesis of 60 Fe through studies of meteorites and ore formation. In the last decade, advances in mass spectrometry have allowed the detection and quantification of minute, naturally occurring variations in the ratios of the stable isotopes of iron.
Iron-60 is an iron isotope with a half-life of 2.6 million years, but was thought until 2009 to have a half-life of 1.5 million years. It undergoes beta decay to cobalt-60, which then decays with a half-life of about 5 years to stable nickel-60. Traces of iron-60 have been found in lunar samples. In phases of the meteorites … See more Naturally occurring iron (26Fe) consists of four stable isotopes: 5.845% of Fe (possibly radioactive with a half-life over 4.4×10 years), 91.754% of Fe, 2.119% of Fe and 0.286% of Fe. There are 24 known radioactive isotopes, … See more The isotope Fe is the isotope with the lowest mass per nucleon, 930.412 MeV/c , though not the isotope with the highest nuclear binding energy per nucleon, which is nickel-62.
