Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Ionic compounds characteristics.
- (A) Made up of positive and negative ions: Correct. Ionic compounds consist of ions held together by electrostatic forces.
- (B) Ionic bonds are non-directional: Correct. The electrostatic attraction in ionic bonds is non-directional, meaning the attraction is the same in all directions.
- (C) Melting point and boiling point are usually low: Incorrect. Ionic compounds typically have high melting and boiling points due to the strong electrostatic forces between ions.
- (D) Usually soft: Incorrect. Ionic compounds are usually hard, not soft, because of the strong ionic bonds.
Step 2: Conclusion. The correct options are (A), (B), and (C).
Final Answer: \[ \boxed{\text{(A), (B) and (C) only}} \]
