What is Metallic Bonding?
Metallic bonding is the force of attraction between the positive metal ions and the delocalised electrons in a metal lattice. The outer shell electrons of the metal atoms are free to move throughout the structure, creating a 'sea' of delocalised electrons.
Board notes: Metallic bonding is the third main type of bonding you need to know. All boards will test your ability to describe the model and use it to explain the characteristic properties of metals.
Step-by-step explanationWorked examples
Worked example 1: Core method
In a piece of copper, the copper atoms lose their outer electrons, which become delocalised. This leaves a lattice of positive copper ions (Cu²⁺) surrounded by a sea of mobile electrons. The attraction between the ions and electrons holds the structure together.
Worked example 2: Exam variation
Now change one detail in the question and keep the same structure: name the Metallic Bonding idea being tested, show the method or evidence, then explain why it answers the command word. This helps GCSE Chemistry students avoid memorising one surface pattern.
Worked example 3: Mark-scheme check
Finish by checking the answer against marks: one point for the correct Metallic Bonding idea, one for accurate working or evidence, and one for a precise final statement. If any step is vague, rewrite it before moving to timed practice.
Mini lesson for Metallic Bonding
1. Understand the core idea
Metallic bonding is the force of attraction between the positive metal ions and the delocalised electrons in a metal lattice. The outer shell electrons of the metal atoms are free to move throughout the structure, creating a 'sea' of delocalised electrons.
Can you explain Metallic Bonding without copying the notes?
2. Turn it into marks
In a piece of copper, the copper atoms lose their outer electrons, which become delocalised. This leaves a lattice of positive copper ions (Cu²⁺) surrounded by a sea of mobile electrons.
Underline the method, evidence, or command-word move that would earn credit in GCSE Bonding & Structure.
3. Fix the likely mark leak
Watch for this mistake: Describing metallic bonding as a bond between individual atoms rather than a lattice of positive ions and delocalised electrons.
Write one correction rule before doing another practice question.

Mini quiz: Metallic Bonding
Three quick checks for revision practice. They are original StudyVector prompts, not official exam-board questions.
Question 1
In one GCSE sentence, explain what Metallic Bonding is testing.
Answer: Metallic bonding is the force of attraction between the positive metal ions and the delocalised electrons in a metal lattice. The outer shell electrons of the metal atoms are free to move throughout the structure, creating a 'sea' of delocalised electrons.
Mark focus: Precise definition and topic focus.
Question 2
A Metallic Bonding question uses an unfamiliar context. What should the answer do before adding detail?
Answer: It should name the process, variable, equation, particle model, or evidence being tested, then explain the result using precise scientific vocabulary.
Mark focus: Method selection and command-word control.
Question 3
A student makes this mistake: "Describing metallic bonding as a bond between individual atoms rather than a lattice of positive ions and delocalised electrons." What should their next repair task be?
Answer: Do one Metallic Bonding question and review the mistake type.
Mark focus: Error correction and next-step practice.

Exam board
How should you use board notes for Metallic Bonding?
Metallic bonding is the third main type of bonding you need to know. All boards will test your ability to describe the model and use it to explain the characteristic properties of metals.
Common mistakes
- 1Describing metallic bonding as a bond between individual atoms rather than a lattice of positive ions and delocalised electrons.
- 2Forgetting that the 'ions' in a metal are positive because they have lost their outer electrons.
- 3Not being able to use the model of metallic bonding to explain the properties of metals, such as conductivity and malleability.

Frequently asked questions
Why are metals good conductors of electricity?
The delocalised electrons in the metallic lattice are free to move and carry an electrical current when a voltage is applied.
Why are metals malleable?
The layers of positive ions in a metal can slide over each other without breaking the metallic bond. This allows the metal to be bent and shaped without shattering.
