Ionic Solids

Mr. Anderson explains ionic solids, their structure, and properties. Ionic solids are composed of ions with static charges, forming a lattice structure. They have high melting points, low vapor pressure, and are brittle. They conduct electricity when melted or dissolved in water. The video compares ionic solids with other types of solids, emphasizing their unique properties.

What type of solid is formed when atoms are only from metals?

• Ionic solid

• Molecular solid

• Metallic solid

• Covalent network solid

What is the primary structural feature of ionic solids?

• Lattice of ions

• Metallic bonds

• Covalent bonds

• Molecular clusters

Which property is NOT typical of ionic solids?

• High melting point

• Low vapor pressure

• Ductility

• Brittleness

Why do ionic solids have a high melting point?

• Weak intermolecular forces

• High vapor pressure

• Strong ionic bonds

• Presence of free electrons

What happens to ionic solids when they are melted?

• They conduct electricity

• They lose their lattice structure

• They become non-polar

• They become brittle

How do ionic solids behave when dissolved in water?

• They remain solid

• They conduct electricity

• They form a non-polar solution

• They become non-conductive

What role does water's polarity play in dissolving ionic solids?

• It repels the ions

• It attracts the ions

• It neutralizes the ions

• It forms covalent bonds with the ions
