1:15 know the structure of an atom in terms of the positions, relative masses and relative charges of sub-atomic particles.1:14 know what is meant by the terms atom and molecule.1:13 practical: investigate paper chromatography using inks/food colourings.

1:12 understand how to use the calculation of Rf values to identify the components of a mixture.1:11 understand how a chromatogram provides information about the composition of a mixture.1:10 describe these experimental techniques for the separation of mixtures: simple distillation, fractional distillation, filtration, crystallisation, paper chromatography.1:09 understand that a pure substance has a fixed melting and boiling point, but that a mixture may melt or boil over a range of temperatures.1:08 understand how to classify a substance as an element, a compound or a mixture.1:07 (Triple only) practical: investigate the solubility of a solid in water at a specific temperature.1:06 (Triple only) understand how to plot and interpret solubility curves.

1:05 (Triple only) know what is meant by the term solubility in the units g per 100g of solvent.

1:04 know what is meant by the terms: solvent, solute, solution, saturated solution.

1:03 understand how the results of experiments involving the dilution of coloured solutions and diffusion of gases can be explained.

1:02 understand the interconversions between the three states of matter in terms of: the names of the interconversions, how they are achieved and the changes in arrangement, movement and energy of the particles.

1:01 understand the three states of matter in terms of the arrangement, movement and energy of the particles.
