Properties of Ionic Bonding and Crystal Structure

These flashcards cover the key concepts and definitions related to ionic bonding and the properties of ionic compounds as discussed in the lecture.

Ionic Bond

A bond formed due to the electrostatic attraction between positively and negatively charged ions.

Characteristics of Ionic Bonds

An ionic bond is non-directional and its strength of interaction depends on distance, not direction.

Dissolving Ionic Bonds

Ionic bonds are broken when the substance is dissolved in a polar solvent or when melted.

Ionic Compounds Structure

Ionic compounds form crystals, which are solids with plane surfaces arranged at regular angles.

Crystal Lattice

The geometrical structure formed by the regular arrangement of ions in a crystalline substance.

Unit Lattice Cell

The simplest repeating unit within a crystalline solid that forms the giant structure.

Coordination Number

In NaCl, one sodium ion is surrounded by six chloride ions, giving a 6:6 coordination.

Enthalpy Change in Ionic Crystal Formation

Each process in forming ionic crystals from elements involves an enthalpy change, such as atomization energy.
