  1. Chemistry 1

  2. The structure of the atom Describe the structure of an atom

  3. Mass and atomic number MASS NUMBER 4 He SYMBOL 2 PROTON (ATOMIC) NUMBER = • How do you find out the number of • Protons? • Electrons? • Neutrons?

  4. Elements, compounds & mixtures • What are • Elements? • Compounds? • Mixtures?

  5. Periodic table Pb Ta Fr Ra Cs Ba La Hf W Tl Re Os Ir Pt Au Bi Sn Po Cd Ne F At Rn Rb Sr Y Zr Nb Mo Tc Ru Rh Pd Ag In Sb Hg I H K Ca Sc Ti V Cr Mn Fe Co Ni Cu Zn Ga Xe Te As Ge Br Kr Na Mg Al Si Se S P Ar Li Be B C N O Cl • Where are the • Reactive metals? • Transition metals? • Non metals? • Noble gases? Mendeleev He Columns called groups Rows called periods

  6. Electron structure 39 K 19 Nucleus Describe how to work out the electron configuration of an element

  7. Covalent bonding Give 4 facts about covalent bonding

  8. Ionic bonding Na Cl Give 4 facts about ionic bonding + - Na Cl

  9. Limestone Limestone is a sedimentaryrock made up of mainly calcium carbonate. It’s cheap and easy to obtain by quarrying. What is limestone? How is it obtained? Give 4 uses of limestone

  10. Limestone What are the pros and cons of quarrying?

  11. The “Limestone Cycle” Calcium Carbonate (CaCO3) + water calcium oxide + carbon dioxide CaO (quicklime) + CO2 calcium hydroxide Ca(OH)2 (slaked lime) How is limestone converted into calcium oxide? How is calcium oxide converted into calcium hydroxide? How is calcium hydroxide converted into limestone?

  12. Metal extraction Metals can either be found nativein the ground (e.g. gold) or are found as metal ores (e.g. iron = haematite, aluminium = bauxite) potassium sodium calcium magnesium aluminium carbon zinc iron lead copper silver gold What are the 3 ways of extracting metals? increasing reactivity

  13. Reduction carbon zinc iron lead copper What is reduction?

  14. Electrolysis ---- potassium sodium calcium magnesium aluminium carbon Give 5 facts about electrolysis + + + + Cu2+ Cu2+

  18. Copper, Aluminium and Titanium For each metal give a property and a corresponding use

  19. Alloys Gold mixed with copper Aluminium mixed with magnesium and copper Aluminiun mixed with chromium What is an alloy? Why are alloys better than pure metals?

  20. Using Iron Steel with chromium and nickel is called stainless steel Steel with a high carbon content is strong but brittle Steel with a low carbon content is easily shaped How is iron obtained? What are the problems of this iron? How can this iron be improved?
