Ge74
Ge-74, or Ge-74, is a stable isotope of the element germanium (atomic number 32). It has a mass number of 74, consisting of 32 protons and 42 neutrons. Ge-74 is one of the five naturally occurring stable germanium isotopes, the others being Ge-70, Ge-72, Ge-73, and Ge-76. In terrestrial materials it occurs as part of the natural isotopic composition of germanium, with its exact fractional abundance varying slightly between samples.
Ge-74 is not radioactive and has an effectively infinite half-life, making it stable on geological timescales.
In addition to its natural occurrence, Ge-74 is relevant in isotopic and geochemical studies that rely on
Overall, Ge-74 is a stable, naturally occurring isotope that contributes to the isotopic diversity of germanium
