Properties of Ionic Compounds
MaChemGuy・4 minutes read
Ionic compounds are formed through ionic bonding, creating a strong electrostatic attraction in a giant lattice structure with high melting and boiling points. While solid, ions are fixed preventing electrical conductivity, but when the lattice is broken, mobile ions enable the conduction of electricity.
Insights
- Ionic compounds are formed through ionic bonding, where atoms exchange electrons to create charged ions that are held together by strong electrostatic forces, resulting in a lattice structure with high melting and boiling points.
- The fixed nature of ions in the lattice structure of solid ionic compounds inhibits electrical conductivity, but when the lattice is disrupted, either by melting or dissolving, the mobile ions enable the conduction of electricity, distinct from the movement of electrons.

Ionic Compounds: Strong Bonds, High Melting Points
- Ionic compounds form through ionic bonding, where a sodium atom transfers an electron to a chlorine atom, resulting in a sodium ion with a positive charge and a chloride ion with a negative charge, leading to an attraction between the oppositely charged ions forming a giant lattice structure.
- Due to the strong electrostatic attraction in the giant ionic lattice structure, ionic compounds have high melting and boiling points, requiring a significant amount of energy to break the bonds between the ions.
- In the solid state, ions in the lattice structure are fixed, preventing electrical conductivity, but when the lattice is broken through melting or dissolving in water, the mobile ions allow for the conduction of electricity, as opposed to the movement of electrons.
