This document contains notes from chemistry lessons on topics related to the periodic table and transition metals. It includes assignments on writing formulas for period 3 oxides and chlorides, explaining bonding and predicted structures. There are also sections on the reactions of chlorine and water, transition metal electron configurations, colored compounds formation, variable oxidation states, ligand bonding, and catalytic actions of transition metals.

1. Syllabus Periodicity HL
Homework: Draw a colourful schematic, including equations of
both the Contact and the Haber Process 

2. Syllabus

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. Reactions of Chlorine with
water.
 Cl₂ (g) + H₂O (l) → HOCl (aq) + H+ (aq) + Cl- (aq)

5. Consolidation
 Pg. 78 Green, Damji

6. Starter
 Write out the electron conifguration for the first row of
transition elements.
 YES you can use noble has notation 

7. Weird after Argon 

8. Formation of Coloured
Compounds

9. Why Coloured Compounds ?

10. D-orbital splitting

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. 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. Complex Ion Formation

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 
