Isotopes are distinct nuclear species (or nuclides) of the same chemical element. They have the same atomic number (number of protons in their nuclei)...

observationally stable isotopes: 204Pb, 206Pb, 207Pb, 208Pb. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide. The three isotopes lead-206...

Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced...

taken advantage of in isotope geochemistry and other fields. Normally, the focus is on stable isotopes of the same element. Isotopic fractionation can be...

The isotopic shift (also called isotope shift) is the shift in various forms of spectroscopy that occurs when one nuclear isotope is replaced by another...

Carbon (6C) has 14 known isotopes, from 8 C to 20 C as well as 22 C , of which 12 C and 13 C are stable. The longest-lived radioisotope is 14 C , with...

occurring isotopes, sometimes denoted 1 H , 2 H , and 3 H . 1 H and 2 H are stable, while 3 H has a half-life of 12.32(2) years. Heavier isotopes also exist...
