Here's a breakdown:
* Electrostatic attraction: This refers to the force of attraction between opposite charges.
* Atoms or groups of opposite charge: In ionic compounds, one atom (or group of atoms) loses electrons, becoming positively charged (cation), while another atom (or group of atoms) gains electrons, becoming negatively charged (anion). These opposite charges attract each other.
Key characteristics of ionic compounds:
* High melting and boiling points: Due to the strong electrostatic forces holding them together.
* Solid at room temperature: Again, due to the strong forces.
* Conduct electricity when dissolved in water or melted: The ions become free to move and carry an electrical current.
* Often form crystal lattices: The regular arrangement of ions maximizes the electrostatic attraction.
Examples of ionic compounds:
* Sodium chloride (NaCl): Table salt, formed by the attraction of sodium cations (Na+) and chloride anions (Cl-).
* Calcium carbonate (CaCO3): Found in limestone and seashells, formed by calcium cations (Ca2+) and carbonate anions (CO32-).
* Magnesium oxide (MgO): Used in insulation and cement, formed by magnesium cations (Mg2+) and oxide anions (O2-).
