Metallic Bonding Revision

What property of metals explains why they readily become cations

• Low ionisation energy

• High ionisation energy

• They have electrostatic attraction

• The valence electrons are high energy

Match the following with the correct explanations

• Metals contain mobile and charged particles. (current = movement of charge)

• Electrical conductivity

• Layers of ions remain held together by the delocalised electrons between them. resisting a force

• High melting/boiling points

• Closely packed metal ions and delocalised electrons can transmit vibrations along the lattice

• Heat conductivity

• The electrostatic forces between the positive metal ions and the delocalised electrons are strong.

• Hardness

• The electrostatic forces between the positive metal ions and the delocalised electrons are strong.

• Ductility and Malleability
