The force of attraction between particles with opposite electric charges.
Used by AQA, Edexcel and OCR
Specification 4.2.1.3 · Paper 1
Specification 1.27, 1.33 · Paper 1, Paper 2
A force of attraction between particles with opposite electric charges.
Revise: Ionic Lattice StructureA positive ion attracts nearby negative ions, while a negative ion attracts nearby positive ions. This attraction is an electrostatic force because it acts between electric charges.
The force of attraction or repulsion between electrically charged particles.
Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
A force caused by the attraction or repulsion between electrical charges.
Revise: Ionic bonding natureLines or arrows in a model can indicate attractions between neighbouring ions, but they are not physical connectors: the bond is an electrostatic force.
A force between electrically charged particles; opposite charges attract and like charges repel.
Describe ionic bonding as a strong electrostatic force of attraction between oppositely charged ions, not simply as the transfer of electrons.
Describe an ionic bond as a strong electrostatic force of attraction between oppositely charged ions. Do not describe it merely as electron transfer: transfer forms the ions, while attraction between them is the bond.
For melting or boiling points, link every step: giant lattice → strong electrostatic forces between oppositely charged ions → much energy needed to overcome these forces → high melting and boiling points.
