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.
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.
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…….
