Neutron-poor nuclides with atomic numbers less than 83 tend to decay by either electron capture or positron emission.
This calculation helps us understand the fascination of nuclear reactions.
The energy released when natural gas is burned is about 800 k J/mol.
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.
He argued that a neutron could decay to form a proton by emitting an electron.
