Spontaneous Decay of Unstable Nuclei (HSC SSCE Physics): Flashcards

Random, uncontrollable process where unstable nuclei emit radiation

Alpha ($\alpha$), beta ($\beta$), gamma ($\gamma$)

Much stronger than electrostatic force, works over short distances

Total number of protons and neutrons in nucleus

Number of protons in nucleus

Same protons, different neutrons

Nucleus mass less than sum of individual nucleon masses

$A$ decreases by 4, $Z$ decreases by 2

$A$ unchanged, $Z$ increases by 1

$A$ unchanged, $Z$ decreases by 1
