Chemical bonds (ionic, covalent, metallic)
Chemistry · Bonding
Three ways to bond
Switch between the bond types and focus on what happens to the electrons.
Ionic bonding
metal + non-metal
Electrons are transferred and the particles involved in the bonding are oppositely charged ions.
Relationship matrix
Tap any cell to reveal it. Tap a column header to read one property down every item.
Each cell hides a short answer and the reason behind it. Predict before you tap.
Build the metallic picture
Follow how the structure and electrons fit together.
- Outer electrons delocaliseElectrons from the outer shells of the metal atoms become delocalised rather than remaining attached to one atom.
- Electrons move throughoutBecause the electrons are delocalised, they are free to move through the whole structure.
- The structure bonds stronglyThe sharing of these delocalised electrons through the structure gives rise to strong metallic bonds.
Recognise the bonding
Use the diagram clues rather than guessing from a name.
A diagram shows atoms in a giant regular pattern with delocalised electrons free to move throughout. What bonding is it showing?
Bonding language
Retrieve the distinction before turning each card.
WHAT YOU'VE LEARNED
A quick recap of today's lesson.
Three strong bonds, distinguished by the particles involved and what happens to the electrons.

How this lesson was checked. This AQA GCSE Chemistry (specification 8462)lesson was published through Lightbulb Learning's human-designed editorial process — the educational standards, accuracy rules and publication checks it must pass were authored and approved by Philip Halpin. It passed subject-specific assessment, automated educational checks and technical publication verification before going live (publication checks completed 13 August 2026). Published pages are monitored, human spot-checking is ongoing across the lesson library, and anything found wrong is corrected or withdrawn. How our lessons are made and checked. Spotted a mistake?
