Quick explanation

Describe polymers as very large molecules made from atoms linked by covalent bonds

  • This point belongs to How bonding and structure are related to the properties of substances, especially Polymers.
  • You need to be able to describe polymers as very large molecules made from atoms linked by covalent bonds.
  • The key ideas to know are covalent bond, large molecule, and polymer.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect Polymers to exam-style questions, flashcards, and revision notes for How bonding and structure are related to the properties of substances.

Quick student answer

What are polymers?

Direct answer

In Chemistry, this page helps you answer questions about polymers within How bonding and structure are related to the properties of substances. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are polymer and covalent bond.

Key terms

  • polymer: In Polymers, polymer means a very large molecule made from atoms linked by covalent bonds. This matters in How bonding and structure are related to the properties of substances because it supports the learning objective to describe polymers as very large molecules made from atoms linked by covalent bonds. Use polymer only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
  • covalent bond: In Polymers, covalent bond means the chemistry idea used to describe polymers as very large molecules made from atoms linked by covalent bonds. Use this term specifically in How bonding and structure are related to the properties of substances when explaining this objective, so it is not confused with a broader bonding, structure, or materials term.

Common trap

Misunderstanding Polymer Structure: Emphasize that polymers are characterized by their large size and are made from many atoms linked by covalent bonds.
