erbium170

Erbium-170, written as 170Er, is a stable isotope of the lanthanide element erbium (Er). It contains 68 protons and 102 neutrons, giving a mass number of 170. It is one of the six naturally occurring, stable isotopes of erbium, the others being 162Er, 164Er, 166Er, 167Er, and 168Er.

Because it is stable, 170Er does not undergo radioactive decay under normal conditions and has no known radioisotopic applications.

In nature, erbium exists as a mixture of stable isotopes, including 170Er, which occurs with a nonzero abundance within natural erbium. It is not produced as a radiogenic nuclide and has no dedicated medical or industrial radiotracer uses.

In scientific contexts, stable isotopes such as 170Er contribute to discussions of nuclear structure and isotopic abundances. They are relevant for high-precision mass spectrometry, geochemical tracing, and materials science studies involving erbium-containing compounds, where the different stable isotopes can influence subtle physical properties and spectral characteristics.
