1

Structural isomer

Same molecular formula but different structural formula

2

Stereoisomers

Same structural formula but different arrangement of atoms in space

3

Racemic mixture

A 50/50 mixture of two enantiomers

4

Transition element

An element that forms at least one ion with an incomplete D-subshell

5

Monodentate ligand

Donates one pair of electrons to a transition metal ion

6

Complex ion

A transition metal ion coordinately bonded to one or more ligands

7

Coordinate bond

A shared pair of electrons (covalent bond) where both electrons are donated by one atom

8

Coordination number

The number of coordinate bonds formed to a central transition metal ion

9

Bidentate ligand

An ion or molecule that donates two electron pairs from different atoms (on the same molecule)

10

Multidentate ligand

An ion or molecule that forms two or more coordinate bonds (to the central transition metal ion)

11

Ligand substitution effect

One type of ligand are replaced by any other type of ligand
