Chemsheets Atomic Structure -

These resources are particularly valued because they are "exam-style." They do not shy away from the mathematical rigors of the subject, ensuring that a student who completes a Chemsheet on atomic structure is prepared for whatever an exam board might throw at them.

| Question Type | Method | | :--- | :--- | | | Mass number – atomic number | | Identify isotope pair | Same atomic number, different mass number | | Calculate (A_r) | Use weighted mean formula | | Write configuration of element | Follow shell or sub-shell order | | Compare two atoms | Same Z? Same element. Different A? Isotopes. | | Mass spectrum – find (A_r) | (m/z × height) sum / total height | chemsheets atomic structure
