Scientists found an unexpected nuclear energy shift in radioactive lanthanum isotopes, challenging existing models and ...

However as the number of protons increases, more neutrons are needed to keep the nucleus stable. For example lead, lead-206 has 82 protons and has 124 neutrons.

When unstable nuclei undergo change they give off radiation. Atoms which have unstable nuclei are radioactive and are called radioisotopes or radionuclides. The change that an unstable nucleus ...

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic masses of ...

Nuclear binding energies of neutron-rich radioactive nuclei are essential ... much energy is required to remove one neutron from the nucleus of a given isotopes. "It gives information on the ...

A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different isotope. The rate at which nuclei decay is constant. Half-life describes ...
