Short explanation

Write formulae and balanced symbol equations for reactions in the Chemistry specification. This objective belongs to Atoms, elements and compounds within A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes for AQA GCSE Chemistry 8462. A strong answer should use formula accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
