Salt compounds are generally

• A. Ionic
• B. Covalent molecules
• C. Noble gases
• D. Metals

Answer: (A)

Salt compounds are generally ionic because they form from a metal transferring electrons to a non-metal, creating positively charged and negatively charged ions. These ions are pulled together by strong electrostatic forces, arranging into a repeating lattice. This ionic bonding gives salts high melting points and the ability to conduct electricity when melted or dissolved in water, since the ions become free to move.

Understanding the alternatives helps: covalent molecules rely on sharing electrons and do not form the solid lattice of oppositely charged ions; noble gases are very unreactive and do not readily form salts; metals themselves aren’t salts but can participate in reactions that produce ionic compounds with non-metals.
