Ionic Bonding and Properties

Flashcards covering key vocabulary related to ionic bonding, including definitions and concepts from the lecture notes.

Ionic Compounds

Compounds that contain ions, usually formed by a reaction between a metal and a non-metal.

Ionic Bond

Electrostatic attraction between positive and negative ions.

Crystal Lattice

An orderly arrangement of ions in an ionic crystal that minimizes potential energy.

Hydrated Crystals

Salts that have water chemically bonded to the ions in the crystal structure.

Trends in Ionic Radii

Describes how ionic size changes with the loss or gain of electrons.

Cation

A positively charged ion that is smaller than its parent atom due to the loss of electrons.

Anion

A negatively charged ion that is larger than its parent atom due to the gain of electrons.

Fajan's Rules

Predicts the covalent character of ionic compounds based on cation charge density and anion polarisability.

Melting Point of Ionic Compounds

Generally high due to strong electrostatic forces between ions.

Electrical Conductivity of Ionic Compounds

They conduct electricity when melted or dissolved in water.
