What you practice

These are the CBSE Class 12 The d- & f-Block Elements skills this quiz is built around.

Explain variable states, colour, magnetism and catalysis by d electrons.
Compare lanthanoid contraction and actinoid behaviour.
Describe permanganate and dichromate preparation and uses.

A useful tip

Partly filled d orbitals allow d-d transitions that often produce colour. Empty or full d shells rule out that mechanism, but not every source of colour: permanganate is coloured by charge transfer despite manganese having a d-zero configuration.
