How transition metals differ from Group 1, their ions with different charges, their coloured compounds and their use as catalysts.
What you will learn
- Compare transition metals with Group 1 metals using data
- Work out the charge on a transition metal ion from a formula
- Name the colours of common transition metal solutions
- Explain why transition metals are useful catalysts
Where they are, and which boards ask
The transition metals are the central block of the periodic table, between Group 2 and Group 3.
The ones you need are chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni) and copper (Cu).
- AQA (Chemistry 8462, section 4.1.3): Chemistry only. Compare them with Group 1, and know their ions, colours and catalysts.
- Edexcel (Chemistry 1CH0, 5.1C): Chemistry only. Know their high melting points and densities, coloured compounds and catalysts, with iron as the example.
- OCR Gateway (C4.1): the same typical properties, in the topic on predicting reactions.
The rest of this lesson and its 21 practice questions are locked.
