A Uranium-(238,92) nucleus decays into a Thorium-234 nucleus by the emission of an alpha-particle. Given Thorium has a chemical symbol Th build a nuclear equation.

A nuclear equation expresses all of the elements before (LHS of = sign) and after (RHS of = sign) the reaction in terms of nucleon (N) and proton number (A), both quantities are conserved during the reaction...
