Ionic Compound
An ionic compound is a compound formed by attraction between oppositely charged ions.
Practice This ConceptMain explanation
Teacher explanation
Ionic compounds have strong electrostatic attraction between positive and negative ions, so they usually have high melting points. In the solid state, ions are fixed in place, so they do not conduct electricity. In molten or aqueous state, ions become mobile and can carry current.
Example
Sodium chloride is an ionic compound.
Simple analogy
Fixed ions cannot carry current; moving ions can.
Common confusion
Students often think an ionic solid conducts electricity because it contains ions, but the ions must be mobile to carry current.
Exam tip
Check the state first: solid ionic compound usually does not conduct, but molten or aqueous ionic compound can conduct.
