Properties of Ionic and Molecular Compounds

Question 1

Properties of ionic compounds

Answer 1

• Hard
• Defined edges (clear break)
• Form crystal lattice
• Very high melting point
• Soluble in water (the ions become free to move)
• Conduct electricity

Question 2

Properties of molecular compounds

Answer 2

• Soft
• Low melting point
• Not soluble in water
• Don’t conduct electricity
