Ionic Bonding and Structure (OCR A-Level Chemistry A): Flashcards

Electrostatic attraction between oppositely charged ions

Positive ions (e.g., $\text{Na}^+$, $\text{Ca}^{2+}$)

Negative ions (e.g., $\text{Cl}^-$, $\text{O}^{2-}$)

Match nearest noble gas configuration

3D structure with each ion attracting opposite charges

6 oppositely charged ions

Strong electrostatic forces throughout lattice

Greater charges = higher melting points

No conduction - ions fixed in lattice

Conducts - ions mobile as charge carriers
