d- and f-Block Elements
Your child will explain why transition metals colour, magnetise and catalyse reactions. The d- and f-block chapter typically carries about seven marks, often a trend-explanation plus a dichromate or permanganate question. Learners study electronic configuration with atomic size, ionisation enthalpy, oxidation states, colour, magnetism and catalytic activity, cover potassium dichromate with potassium permanganate preparation and uses, and survey the lanthanoid alongside actinoid contraction. Three errors surface. Students write configurations that violate half-filled stability. They attribute c
