Nuclei with a higher than desired neutron-to-proton ratios tend to undergo which type of decay?

Hey there!

Nuclei with a high neutron-to-proton ratio usually undergo a beta emission.

Beta emissions, unlike some other types, is radioactive decay throughout these particles, and can have half lives like other types of exponential (usually) decay. Neutrino, along with beta rays, are coming from, or emitted from the nucleus - hence the name.

Hope this helps!
