Sentences with phrase «with different numbers of neutrons»
Stable isotope geochemistry is the study of how physical and chemical processes can cause isotopes — atoms of an element with different numbers of neutrons — to separate (called isotopic fractionation).

For instance, radiocarbon dating determines the age of biological remains based on the ratio between the carbon isotopes (atoms of the same element with different numbers of neutrons) carbon - 12 and carbon - 14 it holds - this proportion changes as radioactive carbon - 14 breaks down while stable carbon - 12 does not.
(Isotopes are species of the same element, albeit with different numbers of neutrons and hence different atomic masses.)
For example; carbon has three isotopes with different number of neutrons; 12C, 13C, 14C.

For this study, the team set out to investigate the timing of supernova dust formation by measuring isotopes — versions of elements with the same number of protons but different numbers of neutrons — in rare presolar silicon carbide grains with compositions indicating that they formed in type II supernovae.
Today is the birthday of Frederick Soddy, an English chemist born in 1877 who pioneered the study of isotopes, elements with the same number of protons but a different number of neutrons.
Isotopes are variants of the same chemical element with different atomic weights due to having different numbers of neutrons, such as the most common carbon isotope, carbon - 12, and a heavier stable isotope, carbon - 13.
