True
Explanation:
In the crystal of an ionic compound, the cations are surrounded by anions so that the charges of the ions are balanced. This very correct.
Ionic compounds are electrically neutral and forms by a charge balance.
- To form an ionic crystal, the charges overall must be balanced and the compound must remain electrically neutral.
- Equal number of charges on the metal and non-metal must cancel out to establish an electrostatic force.
