1. Transition Metal Metal that can form one or more stable ions with a partially
filled d sub-level.
2. Scandium isn't a TM because... Has an empty d-shell when Sc3+
3. Zinc isn't a TM because... Has a full d-shell when Zn2+
4. Which 2 TM have 1 electron in 4s Chromium and Copper
sub-level to give stability?
5. Which sub levels electrons fill up 4s
first and empty first?
6. What physical properties do High density
they have? High melting and boiling points
Similar ionic radii
7. What chemical properties do Form complex ions
they have? Form coloured ions
Are good catalysts
Can exist in variable oxidation states
8. Complex ion Central metal atom/ion surrounded by co-ordinately bond-
ed ligands.
9. Co-ordinate bond (Dative cova- Covalent bond in which both electrons in the shared pair
lent) come from the same atom.
10. Ligand Is an atom/ion/molecule that donates a pair of electrons to
a central metal ion to form a transition metal.
11. Co-ordination number Number of co-ordinate bonds that are formed with the
central metal ion.

13. Lewis Acid Lone pair acceptor.
14. How many small ligands like 6
H20/NH3 can fit around the cen-
tral metal ion?
15. How many larger ligands like Cl- 4
can fit around the central metal
ion?
16. Shape and bond angle of 6 Octahedral, 90 degrees.
Co-ordinate bonds
17. Example of 6 Co-ordinate bond [Fe(H20)6]2+ (hexaaquairon(ii))
complex
18. Shape and bond angle of 4 Tethrahedral, 109.5 degrees.
Co-ordinate bonds
19. Examples of 4 Co-ordinate bond [CuCl4]2- and [CoCl4]2-
