Carbon dating, for example, makes use of the long-lived isotope carbon-14 to determine how old objects are. Under normal circumstances, carbon-14 is produced in our atmosphere via cosmic ray ...

An international research team led by GSI/FAIR, Johannes Gutenberg University Mainz (JGU) and Helmholtz Institute Mainz (HIM) ...

For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written as 12C to reflect its atomic mass. However, about 1 % of the carbon in the Earth’s biosphere has 6 protons and 7 neutrons ...

For example, isotopes are used to map the migration path of butterflies and help protect the resources in their breeding environment. They can also be used in agriculture. Using bio nitrogen ...

For example, carbon occurs naturally in three isotopes: carbon-12, which has six neutrons (plus six protons equals 12; hence the number), carbon-13, which has seven neutrons, and carbon-14, which ...

Stable isotopes can be used by measuring their amounts and proportions in samples, for example in water samples. Naturally-occurring stable isotopes of water and other substances are used to trace the ...
