E.3.8—Decay equations Topic Practice
IB Physics syllabusPhysics SL/HLFirst assessment 2025

Practise decay equations by balancing proton and nucleon numbers, adding the correct beta particle, and following successive decay steps.

How this is tested

  • complete a decay equation by conserving proton number and nucleon number on both sides
  • add the correct emitted beta particle and the matching neutrino or antineutrino in the equation
  • follow successive alpha and beta steps to decide the final proton and neutron numbers
