stable and unstable nuclei ☆

what is the role of the strong nuclear force

it keeps the nucleus stable

what is short-range attraction up to

approx. 3 fm

what is very short-range attraction up to

closer than approximately 0.5 fm

what type of decay has an unstable nuclei

alpha and beta decay

what do equations for alpha and β− decay have to include

the neutrino

why was the existence of the neutrino was hypothesised

to account for conservation of energy in beta decay

the SNF graph

what does unstable nuclei have

too many of either protons, neutrons or both

where does alpha decay occur

in large nuclei

where does beta-minus decay occur

when there’s too much neutrons
