(HL)S3.2: Further functional groups

complementary colours

two colours opposite one another on a colour wheel

complex ion

Complex composed of a central d-block metal ion coordinate bonded to electron-rich ligands

coordination number

Number of lone pairs bonded to the metal ion

electron repulsion

electrons try to move as far away from each other due to the repelling negative charges

ligand

Neutral molecule or anion with a non-bonding pair of electrons (commonly water)

monodentate ligand

One non-bonding electron pair

oxidation state

Akin to ionic charge, it represent the number of electrons gained or lost in order to form a covalent bond with another atom

polydentate ligand

More than one non-bonding electron pair

transition metal

Elements that form ions with an incomplete d-orbital in one of more of its oxidation states

valence shell

Outermost energy level of an atom

visible light

the part of the electromagnetic spectrum the human eye can see. contains wavelengths from 400nm to 700nm
