Lesson Title: Today we are learning about
What is metallic bonding?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Metals consist of giant structures of atoms arranged in a regular pattern.
  2. The electrons in the outer shell of metal atoms are delocalised and so are free to move through the whole structure.
  3. The sharing of delocalised electrons gives rise to strong metallic bonds. The bonding in metals may be represented in the following form: (diagram)
  4. Students should be able to recognise substances as metallic giant structures from diagrams showing their bonding.
  5. Students should be able to recognise that atoms themselves do not have the bulk properties of materials
Think about how you can match the needs of ALL students
Keywords:
  • Delocalised electrons: are electrons in a molecule, ion or solid metal that are not associated with a single atom (1)
  • Ion: an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. (1)
  • Lattice: a regular repeated three-dimensional arrangement of atoms, ions, or molecules in a metal or other crystalline solid. (1)
  • Metallic bond: is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions. (1)

AFL/Key Questions:
  1. What is the structure of a metal like?
    Metals consist of giant structures of atoms arranged in a regular pattern.
  2. How are the electrons in the outer shell of metal atoms arranged?
    The electrons in the outer shell of metal atoms are delocalised and so are free to move through the whole structure.
  3. Why are metallic bonds so strong?
    The sharing of delocalised electrons gives rise to strong metallic bonds. The bonding in metals may be represented in the following form: (diagram)
  4. Describe the structure of metallic bonding?
    positive atoms surrounded by negatively charged delocalised electrons
  5. When compared with the properties of materials, do atoms have the same bulk properties?
    Atoms themselves do not have the bulk properties of materials.

Remember to check for PROGRESS
Starter Activity Differentiation and Challenge question/task
  • Students to copy and complete the keywords.
  • Teacher reveals missing letters; Students correct mistakes;
  • Discuss the scientific meanings of the words.
  • Students to write down the definitions of the most important / new keywords.
  • Discuss the 'Memory Anchor'.
    • What does it show?
    • How does it relate to the what we are learning about today (title)?
Think about PACE – Develop, consolidate and deepen knowledge, skills and understanding
