The correct response for why sugar is not considered an ionic substance is:
- Because it does not contain charged particles and is made up of non-metals.
Sugar (sucrose) is a covalent compound composed of carbon (C), hydrogen (H), and oxygen (O) atoms, which are all non-metals. Unlike ionic substances, which are formed from the electrostatic attraction between charged ions (typically between metals and non-metals), sugar molecules are held together by covalent bonds where electrons are shared rather than transferred. Therefore, sugar does not form ions in solution, which distinguishes it from ionic substances.
