Hl periodicity

  1. 1. Syllabus Periodicity HLHomework: Draw a colourful schematic, including equations of both the Contact and the Haber Process 
  2. 2. Syllabus
  3. 3. Task One [Study Guide 15/16] Write out the formulae of the oxides and chlorides of period 3 Each ELEMENT must have its own card. On the back of the card record :-  Physical state  Conductivity ( when molten )  Drawthe bondedstructure of each of the compounds you predict will be formed. Include an explanation of the above with reference to bonding.
  4. 4. Reactions of Chlorine with water. Cl₂ (g) + H₂O (l) → HOCl (aq) + H+ (aq) + Cl- (aq) http://www.youtube.com/watch?v=Mx5JJWI2aaw
  5. 5. Consolidation Pg. 78 Green, Damji
  6. 6. Starter Write out the electron conifguration for the first row of transition elements. YES you can use noble has notation 
  7. 7. Weird after Argon 
  8. 8. Formation of Coloured Compounds
  9. 9. Why Coloured Compounds ?
  10. 10. D-orbital splitting
  11. 11. Variable Oxidation State Titanium- +2, +3, +4 Vanadium- +2, +3, +4, +5 Chromium- +2, +3, +6 Manganese- +2, +3, +4, +5, +6, +7 Iron- +2, +3 Cobalt- +2, +3 Nickel- +2, +3, +4 Copper- +1, +2 When Transition Metals form positive ions they loose their electrons from the 4s sub-shell first, then the 3d sub-shell. Give electronic structures for the ions in the following: copper(II)oxide, Copper(I)oxide, iron(II)sulphate, Iron(III)chloride, chromium(III)chloride.
  12. 12. Ligand TMs have partially filled, and vacant p and dorbitals. These can accept a pair of electrons to form a dative covalent bond. Common examples are…….
  13. 13. Complex Ion Formation
  14. 14. Catalytic Action Vanadium Pentoxide in Contact process Fe in Haber process and heme Ni in alkenes to alkanes Co in Vit B12 Pd/Pt in catalytic converters Include Economic significance of catalysts 
