Ligands

What is a ligand?
A molecule/ion that bonds to a central metal atom/ion to form a complex
1 of 9
What charge can ligands take?
Either neutral or negative
2 of 9
Why can ligands form dative covalent bonds to the metal atom/ion?
They have a lone pair of electrons on at least one of the atoms in the molecule
3 of 9
What is a monodentate ligand?
Ligands that have only one atom able to bond to a central metal atom/ion.
4 of 9
What is a bidentate ligand?
Ligands that have two atoms capable of binding to a central metal atom or ion.
5 of 9
What is a polydentate ligand?
A ligand molecule with more than one donor atom
6 of 9
What is a complex ion?
An ion that consists of a metal atom or ion in the centre that's surrounded by ligands.
7 of 9
What is the charge of a complex ion?
The sum of the charges of the metal ion and the ligands
