Faulkner’s Chemistry Exam Revision Checklist This is a summary of the Exam content. It does not mention everything specifically and so you should use it to structure your revision alongside your notes. Rate of Reaction □ alculate the mean rate of a reaction from given information about the quantity of a reactant used or the quantity of a product formed and the time taken? □ draw, and interpret, graphs showing the quantity of product formed or quantity of reactant used up against time? □ draw tangents to the curves on these graphs and use the slope of the tangent as a measure of the rate of reaction? □ calculate the gradient of a tangent to the curve on these graphs as a measure of rate of reaction at a specific time? □ predict and explain using collision theory the effects of changing conditions of concentration, pressure and temperature on the rate of a reaction? □ explain the effects of changes in the size of pieces of a reacting solid in terms of surface area to volume ratio? □ use simple ideas about proportionality when using collision theory to explain the effect of a factor on the rate of a reaction? □ identify catalysts in reactions from their effect on the rate of reaction and because they are not included in the chemical equation for the reaction? □ explain catalytic action in terms of activation energy? Atoms, Elements and Compounds. □ use the names and symbols of the first 20 elements in the periodic table, the elements in Groups 1 and 7, and other elements. □ □ □ name compounds of these elements from given formulae or symbol equations? write word and balanced chemical equations for reactions? write balanced half equations and ionic equations where appropriate? Mixtures □ □ describe, explain and give examples of the processes of separation? suggest suitable separation and purification techniques for mixtures when given appropriate information? The Atom. □ □ □ Know why the new evidence from Rutherford’s scattering experiment led to a change in the atomic model? describe the difference between the plum pudding model of the atom and the nuclear model of the atom? calculate the numbers of protons, neutrons and electrons in an atom or ion, given its atomic number and mass number? □ relate the size and scale of atoms to objects in the physical world? The Periodic Table □ explain that the position of an element in the periodic table is related to the arrangement of electrons in its atoms and hence to its atomic number? □ predict possible reactions and probable reactivity of elements from their positions in the periodic table? □ □ describe Mendeleev’s steps in the development of the periodic table? □ explain that the atomic structure of metals and non-metals relates to their position in the periodic table? explain that the reactions of elements are related to the arrangement of electrons in their atoms and hence to their atomic number? □ explain the differences between metals and non-metals on the basis of their characteristic physical and chemical properties? □ Know that the properties of the elements depend on the outer shell of electrons of the atoms? □ □ predict properties from given trends down a group? describe the difference of transition metals compared with Group 1 in melting points, densities, strength, hardness and reactivity with oxygen, water and halogens? Know that many transition elements have ions with different charges, form coloured compounds and are useful as catalysts? □ Chemical Bonds. □ explain chemical bonding in terms of electrostatic forces and the transfer or sharing of electrons? Ionic Bonding and compounds. □ draw dot and cross diagrams for ionic compounds formed by metals in Groups 1 and 2 with non-metals in Groups 6 and 7? □ work out the charge on the ions of metals and non-metals from the group number of the element? □ deduce that a compound is ionic from a diagram of its structure in one of the specified forms? □ describe the limitations of using dot and cross, ball and stick, two and three dimensional diagrams to represent a giant ionic structure? □ work out the empirical formula of an ionic compound from a given model or diagram that shows the ions in the structure? Covalent Bonding and compounds. □ □ □ recognise common substances that consist of small molecules from their chemical formula? draw dot and cross diagrams for the molecules H2, Cl2, O2, N2, HCl, H2O, NH3 and CH4? represent covalent bonds using a line to represent a single bond? □ □ describe the limitations of using dot and cross, ball and stick, two and three dimensional diagrams to represent molecules or giant structures? deduce the molecular formula of a substance from a given model or diagram in these forms showing the atoms and bonds in the molecule? The three states of matter. □ □ □ □ predict the states of substances at different temperatures given appropriate data? explain the different temperatures at which changes of state occur in terms of energy transfers and types of bonding? recognise that atoms themselves do not have the bulk properties of materials? explain the limitations of the particle theory in relation to changes of state when particles are represented by solid inelastic spheres which have no forces between them? □ Properties of structures □ □ □ □ □ □ Know the properties of giant Ionic structures? use the idea that intermolecular forces are weak compared with covalent bonds to explain the bulk properties of molecular substances? Know the properties of polymers and be able to recognise polymers from diagrams showing their bonding and structure? recognise giant covalent structures from diagrams showing their bonding and structure? Know the structure and properties of metals? explain why alloys are harder than pure metals in terms of distortion of the layers of atoms in the structure of a pure metal? Structure and bonding of diamond □ □ □ □ Know to explain the properties of diamond in terms of its structure and bonding? □ Know the uses of fullerenes, including carbon nanotubes. Know that graphite is similar to metals in that it has delocalised electrons? Know that graphene is a single layer of graphite and so is one atom thick? recognise graphene and fullerenes from diagrams and descriptions of their bonding and structure? Nanoparticles □ □ □ compare ‘nano’ dimensions to typical dimensions of atoms and molecules? evaluate the use of nanoparticles for a specified purpose, given sufficient information? explain that there are possible risks associated with the use of nanoparticles?
