Copper and iron are both transition metals. Give four properties of transition metals that explain why these metals are widely used in construction and engineering.
Written & reviewed by James Millett — Biology (Imperial College London), PGCE Science (University of Cambridge).
Model answer (4 marks)
1. High melting points – they remain solid at high temperatures.
2. Hardness/strength – they resist deformation.
3. Good thermal conductivity – they transfer heat efficiently.
4. Good electrical conductivity – they carry electric current well.
2. Hardness/strength – they resist deformation.
3. Good thermal conductivity – they transfer heat efficiently.
4. Good electrical conductivity – they carry electric current well.
Examiner tips
- Use the exact terms ‘high melting points’, ‘hardness/strength’, ‘thermal conductivity’, ‘electrical conductivity’.
- Number each point to show you’ve covered all four marks.
- Mention the practical benefit (e.g., structural integrity, heat transfer, electrical use).
Common mistakes
- Confusing ‘high melting point’ with ‘low melting point’.
- Using vague words like ‘strong’ without linking to hardness or strength.
- Omitting the word ‘conductivity’ or mixing up heat and electricity.
Mark scheme (4 marks)
- Transition metals have high melting points (so they are suitable for high-temperature applications / maintain structural integrity under heat)
- Transition metals are hard / strong
- Transition metals are good conductors of heat (thermal conductors)
- Transition metals are good conductors of electricity
