-
Use chemical symbols to represent elements and compounds, e.g. Water, Methane, Chlorine
-
Write a word equation and balance it, e.g. Hydrogen and Nitrogen which make Ammonia
Name compounds formed in chemical reactions when given formulae. E.g. State the names of KNO₃, CuSO₄, HBr, MgO
HT Write a balanced half equation, e.g. HT Write the two half equations for: Cu²⁺(aq) + Zn(s) → Zn²⁺(aq) + Cu(s)
HT Write a ionic equation, e.g. CuSO₄(aq) + Zn(s) → ZnSO₄(aq) + Cu(s) (remove the spectator ions)
-
Describe how the following techniques can be used to separate mixtures: Filtration, Simple distillation, Fractional distillation, Chromatography
Choose a suitable separation technique and give a reason for your choice when separating Copper Sulfate from water, Different colour food colourings, A mixture of ethanol and water, A sandy salty water sample
Describe the changes made to the atomic model by the following scientists: Ernst Rutherford, Niels Bohr, James Chadwick. Include the discovery of the atom and Rutherford & Marsden's scattering experiments
-
State the relative charge of protons, neutrons, electrons and the whole atom
-
State the mass of protons, neutrons and electrons.
-
Calculate the number of protons, neutrons and electrons in an atom when given its atomic number and mass number
-
Compare the numbers of protons and neutrons in isotopes, e.g. ¹H and ²H
Calculate the relative atomic mass of an element from isotope abundance data, e.g. Cl-35 (75%) and Cl-37 (25%)
Calculate the relative atomic mass of an element when given the percentage abundance of its isotopes
Represent the electron arrangement of an element, e.g. Oxygen, Iodine
