Transition elements
This chapter defines transition elements as d-block elements forming stable ions with incomplete d sub-shells, highlighting their variable oxidation…
What you'll learn
- Explain what is meant by a transition element.
- Describe how transition elements have variable oxidation states, behave as catalysts, form complex ions, and form coloured ions.
- State the electronic configuration of a first-row transition element and of its ions.
- Predict, using E⦵ values, the feasibility of redox reactions involving transition metal compounds.
- Define the terms ligand and complex.
- Describe the types of stereoisomerism (cis/trans and optical isomerism) shown by complexes, including those with bidentate ligands.
- Explain qualitatively how ligand exchange may occur and describe the term stability constant, Kstab, of a complex ion, and write an expression for the stability constant of a complex.
- Explain the origin of colour in transition element complexes and describe, in qualitative terms, the effects of different ligands on the absorption of light, and hence the colour of a complex.
