Transition Elements

• A transition element is a metal with an ion or a compound with a partially filled d subshell.

• Zinc is not a transion metal but is a d block element because it has a full d subshell. This is shown because its compounds are usually white.

Properties of transition elements:

• Coloured compounds and ions.

• Form complex ions.
• Have catalytic properties.
• Variable oxidation states.
• High melting point.
• High density.
• High tensile strength.
• Show paramagnetism.

A complex

• is formed when a transition metal ion is surrounded by ligands which dative covalent bond with it by donating lone pairs of electrons into vacant d orbitals. The d electrons of the metal ion do not take part in ligand bonding.
