Define atomic number as the number of protons in an atom of an element.

Define atomic number as the number of protons in an atom of an element. This objective belongs to Relative electrical charges of subatomic particles 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 atomic number 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.
