# Metals are described as malleable and good conductors of electricity. Explain why metals have these two properties, in terms of their structure and bonding.

> Eduqas GCSE Chemistry — C2 Bonding, structure and properties · Explain · 4 marks

## Mark scheme (4 marks)

1. Metals contain layers of atoms that can slide over each other
2. This (sliding of layers) is why metals are malleable / can be bent and shaped
3. Metals contain delocalised electrons that are free to move throughout the structure
4. The movement of delocalised electrons carries electrical charge / current through the metal
