How to Make Ionic Compounds

Ionic compounds consist of two or more ions held together by electrical attraction. Ions with a positive charge are called cations while ions with a negative charge are called anions.

You will need

  • Cations
  • Anions
  • Energy for dissociation
  • Energy for ionization

Step 1 Vaporize Vaporize the atoms of a cation-forming element to form a gas.

Step 2 Dissociate Dissociate anion-forming molecules into atoms.

Step 3 Ionize Ionize the cation-forming atoms. With ionization, sodium becomes a positively-charged sodium ion.

Step 4 Transfer Transfer the liberated electrons to the anion-forming atoms. The chlorine atom becomes a negatively charged chlorine ion in this way.

Step 5 Combine Combine the cations and anions in a regular manner to form a crystal. Electrostatic interaction holds the crystal lattice together.
