Ionic Bonding and Giant Ionic Lattices
Electron transfer, ion formation, dot-and-cross diagrams and the link between ionic lattice structure and bulk properties.
How to study for GCSE Chemistry
Move between particle models, equations, calculations, observations and data; practise the specific required activities and paper structure named by your exam board.
Core concepts
Concept 1
Ionic bonding is the strong electrostatic attraction between oppositely charged ions formed after electron transfer.
Exam cue: Use electron configurations and charge balance to derive ion and compound formulae.
Concept 2
A giant ionic lattice contains a repeating three-dimensional arrangement of ions, not discrete molecules.
Exam cue: Describe the electrostatic attraction throughout the lattice when explaining melting point.
Concept 3
Ionic substances usually have high melting points and conduct when molten or dissolved because mobile charged ions can carry current.
Exam cue: Check whether ions are fixed or mobile before predicting electrical conductivity.
Risk pitfalls and guardrails
Describing an ionic bond as the transferred electron itself.
Guardrail: Do not rely on a memorised keyword alone: preserve charges, ratios, units and conditions, and keep single Chemistry separate from Combined Science.
Calling sodium chloride a molecule.
Guardrail: Do not rely on a memorised keyword alone: preserve charges, ratios, units and conditions, and keep single Chemistry separate from Combined Science.
Claiming a solid ionic compound conducts because it contains charged particles.
Guardrail: Do not rely on a memorised keyword alone: preserve charges, ratios, units and conditions, and keep single Chemistry separate from Combined Science.
Memory anchors
Ionic bond
Strong electrostatic attraction between oppositely charged ions.
Cation
A positive ion formed by loss of one or more electrons.
Anion
A negative ion formed by gain of one or more electrons.
Giant ionic lattice
A repeating three-dimensional network of oppositely charged ions.
Ionic conduction
Current flows only when ions are free to move in a melt or solution.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
