How do atoms with stable nuclei differ from atoms with unstable nuclei? Nuclei is the plural of nucleus.

• The number of particles in stable nuclei never changes; the number of particles in unstable nuclei does change 
• Stable nuclei contain equal numbers of protons and neutrons; unstable nuclei do not 
• Stable nuclei emit electrons; unstable nuclei emit protons and neutrons 
• Stable nuclei can be found everywhere; unstable nuclei do not occur in nature
