Steel Story
- Transition Metals
- Is defined as a d-block
element that forms at
least one ion with a
partially filled d-subshell
- Fe [Ar]3d⁶4s²
- Fe²⁺3d⁶4s⁰
- Fe³⁺3d⁵4s⁰
- Electrons get
lost from the 4s
orbital before
the 3d.
- Electrons get
lost from the 4s
orbital before
the 3d.
- Fe³⁺3d⁵4s⁰
- Fe²⁺3d⁶4s⁰
- Chromium and Copper
display different
arrangements as they feel
more stable because of the
half filled and full filled d-sub
shell.
- Cr [Ar]3d⁵4s¹
- Cu [Ar]3d¹⁰4s¹
- Cr [Ar]3d⁵4s¹
- Is defined as a d-block
element that forms at
least one ion with a
partially filled d-subshell
- Chemical Properties
of Transition Metals
- Variable oxidation
states
- Due to the difference between
succesive ionisations in the 3d
and 4s sub shells, therefore
multiple electron loss is
possible.

- Coloured ions
- When the unpaired electron is in
the 3d sub shell absorbes visible
light the unpaired electron gets
excited. As Transition metals are
surrounded by ligands the d orbital
splits up into two energy levels

- Complexes
- Transition metals are able to
form complexes because their
3d orbital can accomodate the
electron donated by the ligand.

- Catalytic Activity
- Metals can act as heterogeneous catalysts,
providing a surface onto which gaseous
reactants can be adsorbed. They can also
act as homogeneous catalysts due to their
different oxidation states.
