Metallic bonding is the attraction between positive metal ions and a sea of delocalised electrons.
- Electrons move freely, so metals conduct
- Layers slide, making metals malleable
- Strong bonds give high melting points

What is Metallic Bonding?
Within Chemistry, which covers atoms, bonding, reactions, the periodic table, organic chemistry and the chemistry of everyday life, this topic explains Metallic Bonding. Chemistry links what you can see in the lab to the particles and bonds behind it, so each topic here shows that link in a model.
Check that you can explain Metallic Bonding in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Metallic Bonding helps you explain why substances behave as they do, from cleaning products and food to medicines.
Metallic Bonding in detail
In a metal, atoms release their outer electrons, forming a lattice of positive ions surrounded by a sea of delocalised electrons. The strong electrostatic attraction between the positive ions and the delocalised electrons is the metallic bond.
This explains the properties of metals: they conduct electricity because the electrons can move freely, conduct heat well, are malleable and ductile because layers of ions can slide over each other without breaking the bond, and have high melting points. Alloys are harder because the different-sized atoms disrupt the layers.
How the interactive helps you understand Metallic Bonding
Watch the bonding model in the interactive. Use any sliders or buttons it offers to change the values and see how the bonding model responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Metallic Bonding.
Real-life uses and examples
- Link Metallic Bonding to everyday products such as cleaning agents, food and medicines.
- Read a chemical equation or diagram and work out what Metallic Bonding shows.
- Explain Metallic Bonding in an exam by linking the particles involved to what you observe.
Common mistakes to avoid
- Mixing up the names of substances or ions when you describe Metallic Bonding.
- Describing what happens without explaining the particles or bonds involved.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
