Give a balanced deuterium–tritium fusion reaction.

Solution & explanation

²₁H + ³₁H → ⁴₂He + ¹₀n + energy. Mass numbers: 2+3 = 4+1; charge numbers: 1+1 = 2+0. High temperature and confinement allow nuclei to approach despite electrical repulsion. Released energy reflects increased binding per nucleon, not loss of charge conservation.
