Born-Haber Cycle
A methodical sequence to determine the formation of an ionic compound from its elements in standard states. Enthalpy of Formation
The heat change when one mole of a compound forms from its elements in their standard states. Sublimation
The process of converting a solid directly into a gas without passing through the liquid state. Ionization Energy
The energy required to remove an electron from a gaseous atom or ion. Enthalpy of Dissociation
The energy needed to break a bond in a molecule to form separate atoms. Electron Affinity
The energy change when an electron is added to a neutral atom in the gas phase. Lattice Energy
The energy released when gaseous ions combine to form an ionic solid. Standard States
The physical state of a substance under standard conditions of 1 atm and 25°C. Sodium Chloride
An ionic compound formed from sodium and chlorine, commonly known as table salt. Cation
A positively charged ion formed by losing electrons. Anion
A negatively charged ion formed by gaining electrons. Gaseous Ions
Ions in the gas phase, crucial for calculating lattice energy in the Born-Haber cycle. Successive Ionization Energies
The energies required to remove each electron in turn from an atom. Chlorine Gas
A diatomic molecule, Cl2, that must be dissociated into atoms in the Born-Haber cycle. Neutral Metal
A metal atom with no net charge, prior to ionization in the Born-Haber cycle.
