What is the definition of a central atom or ion in a coordination entity?
An atom or ion to which ions/groups are bound in a definite geometrical arrangement
Which type of ligand binds to the central metal using a single donor atom?
Monodentate ligand
Which type of ligand forms complexes by using two or more donor atoms to bind to a single metal ion?
Polydentate ligand
What defines an ambidentate ligand?
A ligand that can bind through two different atoms or ions
What characterizes a didentate ligand?
It binds through two donor atoms
Which postulate of Werner's theory states that primary valencies are ionizable and satisfied by negative ions?
The primary valencies are ionizable and satisfied by neutral molecules.
In a coordination compound, the secondary valence is satisfied by ____________.
Neutral molecules or negative ions.
What is a characteristic difference between a double salt and a complex?
Complex ions do not dissociate into their constituent ions when dissolved in water.
What is the main characteristic of a coordination entity in a coordination compound?

In Werner's theory of coordination compounds, what is the primary role of secondary valencies?
Fixed for every metal in a complex.
How do double salts and complexes differ in their behavior when dissolved in water?
Double salts dissociate into simple ions.
