Answer 1

A transition metal ion bonded to one or more Ligands by coordinate bonds

Question 2

A ligand

Answer 2

A molecule of ion that can donate a pair of electrons with the transition metal ion to form a coordinate bond

Question 3

The coordination number

Answer 3

Th total number if coordinate bond formed between a central metal ion and its Ligands

Question 4

Transition element

Answer 4

A d-block element that forms an ion with an incomplete d sub-shell

Question 5

Stereoisomers

Answer 5

Species with the same structural formula but with a different arrangement of atoms in space

Question 6

Ligand substitution

Answer 6

A reaction in which one ligand in a complex ion is replaced by another ligand

Question 7

The stability constant

Answer 7

The equilibrium constant for an equilibrium excising between a transition metal ion surrounded by water Ligands and the complex formed when the same ion has undergone a ligand substitution
