Front

Define transition metals.

Back

Elements that have partially filled d-orbitals and exhibit variable oxidation states.

Front

What is the significance of the d-block in the periodic table?

Back

It contains transition metals, which are known for their ability to form colored compounds and complex ions.

Front

Explain the term 'ligand' in coordination chemistry.

Back

A ligand is a molecule or ion that donates a pair of electrons to a metal ion to form a coordination complex.

Front

What is the role of oxidation states in transition metals?

Back

Oxidation states determine the charge of the metal ion and influence the properties of the compounds formed.

Front

What is a chelating agent?

Back

A chelating agent is a type of ligand that can form multiple bonds to a single metal ion.
