Ionic Solids

What type of elements typically combine to form ionic solids?

• Two non-metals

• Two metals

• A metal and a non-metal

• Metalloids only

What fundamental law describes the electrostatic forces holding ions together in an ionic solid?

• Newton's Law of Universal Gravitation

• Coulomb's Law

• Boyle's Law

• Ohm's Law

Which of the following is a characteristic property of ionic solids in their solid state?

• High vapor pressure

• Ductile

• Good electrical conductors

• High melting point

Why are ionic solids typically brittle?

• They have a low melting point, making them fragile.

• Their ions are tightly packed, preventing movement.

• Shifting the lattice causes like-charged ions to repel, leading to breakage.

• They readily dissolve in water, weakening their structure.
