Naturally occurring ytterbium (70 Yb) is composed of seven stable isotopes: [n 1] 168 Yb, 170 Yb– 174 Yb, and 176 Yb, with 174 Yb being the most abundant (31.83% natural abundance). 30 radioisotopes have been characterized, with the most stable being 169 Yb with a half-life of 32.014 days, 175 Yb with a half-life of 4.185 days, and 166 Yb with a half-life of 56.7 hours.
Natural ytterbium is composed of seven stable isotopes: 168 Yb, 170 Yb, 171 Yb, 172 Yb, 173 Yb, 174 Yb, and 176 Yb, with 174 Yb being the most common, at 31.8% of the natural abundance). Thirty-two radioisotopes have been observed, with the most stable ones being 169 Yb with a half-life of 32.0 days, 175 Yb with a half-life of 4.18 days, and ...
It contains a table of main isotopes and eventually the standard atomic weight. This template is reused in {{Infobox <element>}} as a child Infobox (|child=yes). As of Jan 2023, a 'Main isotope' is conforming MOS:MAINISOTOPE (under construction, see WP:ELEMENTS What is a "Main_isotope"?) Each isotope has its own row, with decay modes:
Archaeological materials, such as bone, organic residues, hair, or sea shells, can serve as substrates for isotopic analysis. Carbon, nitrogen and zinc isotope ratios are used to investigate the diets of past people; these isotopic systems can be used with others, such as strontium or oxygen, to answer questions about population movements and cultural interactions, such as trade.
Radioactive isotope table "lists ALL radioactive nuclei with a half-life greater than 1000 years", incorporated in the list above. The NUBASE2020 evaluation of nuclear physics properties F.G. Kondev et al. 2021 Chinese Phys. C 45 030001. The PDF of this article lists the half-lives of all known radioactives nuclides.
Position-specific isotope analysis, also called site-specific isotope analysis, is a branch of isotope analysis aimed at determining the isotopic composition of a particular atom position in a molecule. Isotopes are elemental variants with different numbers of neutrons in their nuclei, thereby having different atomic masses. Isotopes are found ...
The isotope tables given below show all of the known isotopes of the chemical elements, arranged with increasing atomic number from left to right and increasing neutron number from top to bottom. Half lives are indicated by the color of each isotope's cell (see color chart in each section).
