Ch. 12 - Coordination Chemistry and Colour Flashcards
1
Q
What is the only transition metal that isn’t a solid?
A
Mercury
2
Q
Do transition metals form cations or anions?
A
Cations
3
Q
What is a ligand?
A
Any substance which can act as a Lewis base (neutral or anion), donating electrons to the transition metal cation.
4
Q
What is a monodentate ligand?
A
A ligand co-ordinated to a transition metal through one atom.
5
Q
What is a bidentate ligand?
A
A ligand co-ordinated to a transition metal through two atoms.
6
Q
What is the co-ordination number?
A
Thenumber of atoms attached to the transition metal.
7
Q
When is high spin distribution favoured?
A
When a transition metal is bonded to weak field ligands.
8
Q
When is low spin distribution favoured?
A
When a transition metal is bonded to strong field ligands.
