Question 1

Transition metal

Answer 1

An element which forms at least one stable ion with a partially filled d-subshell

Question 2

Complex

Answer 2

A central metal atom or ion with ligands bonded by co-ordinate bonds

Question 3

Ligand

Answer 3

An ion or molecule with a lone pair of electrons which forms a co-ordinate bond with a central metal atom or ion in a complex

Question 4

Co-ordination number

Answer 4

The number of co-ordinate bonds to a central metal atom or ion in a complex

Question 5

Monodentate

Answer 5

A ligand which uses only one lone pair of electrons to form a co-ordinate bond with a central metal atom or ion in a complex

Question 6

Bidentate

Answer 6

A ligand which uses two lone pairs of electrons to form two co-ordinate bonds with a central metal atom or ion in a complex
