Element Stability• Stable nuclei of elements have a proton to neutron ratio of 1:1 or close to it.
• Unstable nuclei of elements have a larger p to n ratio than 1:1> The protons and neutrons exist in a balance that stabilizes the nuclear force and binding energy.
• Binding energyenergy that binds the nucleons of the nucleus together.
