Ionic compounds usually have:
ALow melting points
BHigh melting points
CNo fixed melting point
DMelting points below 0 C
Answer & Solution
Correct answer: B. High melting points
1. Ionic crystals are held together by strong electrostatic forces.
2. Breaking these forces needs lots of energy.
3. So ionic solids have very high melting points (often >800 K).
4. NaCl melts at about 1074 K.
