The d- and f-Block Elements › Transition Elements (d-Block)The d- and f-Block Elements › Lanthanoids and Actinoids (f-Block)Chapter 24The d- and f-Block Elements
Iron, copper, gold and the rare earths in a phone screen all sit in the middle and the bottom of the periodic table. Their partly filled orbitals explain their colours, their many oxidation states and their use as catalysts. In this chapter you learn the trends of the d-block, the chemistry of potassium dichromate and potassium permanganate, and the lanthanoids and actinoids. Python tabulates electronic configurations and oxidation states.

The Transition Elements
Where the d-block sits and how its electrons are arranged. The trends in size, ionisation enthalpy and oxidation states, and why these elements form coloured, magnetic ions.
Important Compounds of the d-Block
The oxides of the first series, potassium dichromate and potassium permanganate and what they do as oxidising agents, and the alloys and interstitial compounds that metals form.
