📊 Nuclear Decay Equations
Figure 2: Balancing nuclear equations — mass numbers and atomic numbers must balance on both sides.
BALANCING TIP: Add up mass numbers on both sides (must be equal). Add up atomic numbers on both sides (must be equal). The alpha particle is ⁴₂He, the beta particle is ⁰₋₁e.
