Stable Isotopes

Bild vergrößern Stable isotope of hydrogen

The elements of life - hydrogen, oxygen, carbon, nitrogen and sulfur - occur in a number modifications of different weight.

These modifications are called the isotopes of a (given) element. Hence, there are elements that exist in nature as modifications with different atomic weights called isotopes of that element. Stable isotopes of an element are not radioactive because they do not decay.

Isotope numbers are normalized to an international standard and expressed as deviations in terms of one tenth of a percent (‰).
