Answer and see the solution →Explain, in terms of electrostatic forces, how metallic bonding holds a pure metal such as aluminium together. Your answer should refer specifically to the particles involved.
Question 2
5 marks · Hard
Answer and see the solution →Zinc is used to galvanise iron to prevent rusting because it is strong and resistant. Answer the following about the properties of zinc metal and its bonding.
(a)[2 marks]State and explain, in terms of metallic bonding, why zinc conducts electricity.
(b)[2 marks]Zinc can be hammered into thin sheets. Explain why this is possible, referring to its structure and bonding.
(c)[1 mark]Zinc has a high melting point. Explain this property in terms of attraction between its particles.
