Atomic structure and the periodic table
Describe the structure of the atom
Give a definition of an element
Describe how compounds are made and how they can be separated
Use chemical symbols to represent elements and compounds, e.g. Water, Methane, Chlorine
Give a definition of a compound
Describe how you could detect a chemical reaction
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
Write a balanced half equation and ionic equation
Describe the difference between a mixture and a compound
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 Sulphate 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
Explain how the results of the alpha scattering experiment showed that the nucleus was concentrated in the centre of the atom and that it was charged
Recall the approximate radius of the atom and nucleus
State the relative charge of protons, neutrons, electrons and the whole atom
Explain why an atom has no overall charge
State the mass of protons, neutrons and electrons. State how the mass is distributed
Calculate the number of protons, neutrons and electrons in an atom when given its atomic number and mass number
Explain why some atoms of the same element are called isotopes
Calculate the relative atomic mass of an element when given the percentage abundance of its isotopes
Represent the electron arrangement of an element
