**Task:**
Sodium chloride crystals are ionic. Explain what this statement means?
**Answer:**
Ionic structure of NaCl means that its structural element in terms of chemical bound is ion.
Ion is an atom or molecule where the total number of protons is not equal to the number of electrons. So this particle has a positive (excess of protons) or negative (excess of electrons) charge.
This substance splits into ions Na⁺ and Cl⁻ in water.
