Concept introduction:
The pictorial representation of formation of ionic solids from its constituent elements is known as Born-Haber cycle. Following are the steps required to draw Born-Haber cycle of any ionic compound:
Step 1: Solid metal is converted into gaseous isolated atoms. It takes place by process called sublimation.
Step 2: Gaseous molecules are broken down into separate atoms. Energy is supplied to break molecules apart and this is called
Step 3: Isolated metal atoms are converted into respective cations with the help of ionization energy.
Step 4: Anions are formed from gaseous atoms with the help of
Step 5: Ionic compound is formed by the combination of cation and anion. Energy is released in this process.
