Carbon 14 the radioactive nuclide used in dating fossils

It can capture an electron or it can emit a positron.

Nuclei can also decay by capturing one of the electrons that surround the nucleus.

The excess energy associated with this excited state is released when the nucleus emits a photon in the -ray portion of the electromagnetic spectrum.

Most of the time, the -ray is emitted within 10Nuclides with atomic numbers of 90 or more undergo a form of radioactive decay known as spontaneous fission in which the parent nucleus splits into a pair of smaller nuclei.

This calculation helps us understand the fascination of nuclear reactions.

The energy released when natural gas is burned is about 800 k J/mol.
