"A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the number of atoms before and after the change."

Explanation: nuclear reactions conserve nucleon number (mass number) and charge (atomic number), while chemical reactions conserve the number of each type of atom (and thus mass of atoms).
