What effect does chelation have on the stability of metal complexes compared to monodentate ligands?
Increases stability
Why are chelate complexes usually considered non-electrolytes?
They do not dissociate into ions in solution
What property of chelates allows them to exhibit striking colors different from normal salts of the metal?
Coordination number

What is the coordination number of a metal ion?
The number of donor atoms attached to the metal ion
Which of the following is not a type of ligand?
Ionic ligand
How are ligands classified based on their denticity?
Monodentate, bidentate, and polydentate
What is the primary factor that determines the strength of a metal-ligand bond?
The electronegativity difference between the metal and ligand

What is the most common coordination number for metal ions in complex ions?
4 and 6
Which of the following is a characteristic of ligands?
Ligands contain at least one pair of unshared electrons.
What type of ligand is formed when a metal ion binds to two nitrogen atoms in a single molecule?
Bidentate
Which of the following statements about coordination numbers is NOT true?
Coordination number is the minimum number of monodentate ligands that can be bound to the central atom.
Explore the concept of coordination number in complex ion formation, which is the maximum number of monodentate ligands that can bind to the central atom. Learn about the common coordination numbers, ranging from 2 to 8, and the prevalence of even coordination numbers compared to odd ones.
