• Conducts electricity when molten

• Soft and easily scratched

• Brittle

Which of the following is a difference between ionic and covalent compounds?

• Ionic compounds have low melting points, covalent compounds have high melting points

• Ionic compounds conduct electricity when dissolved in water, covalent compounds do not

• Ionic compounds are made of molecules, covalent compounds are made of ions

• Ionic compounds are always gases, covalent compounds are always solids

Which of the following is a simple covalent compound?

Why do giant ionic lattices have high melting points?

• Because the ions are loosely held together

• Because of strong electrostatic forces between oppositely charged ions

• Because they contain covalent bonds
