Properties of Crystalline Solids

What is the regular, repeating arrangement of particles in a crystalline solid called?

• Crystal Lattice

• Molecule Cluster

• Amorphous Structure

• Atomic Bonding

Which type of solid typically has high melting and boiling points due to strong intermolecular forces?

• Amorphous Solids

• Gaseous Solids

• Crystalline Solids

• Liquids

Which of the following is an example of a metallic crystalline solid?

• Sodium Chloride

• Quartz

• Ice

• Copper

It is an example of ionic crystalline solid.

• Copper

• Sodium Chloride

• Diamond

• Sulfur

What is the typical melting and boiling point of amorphous solids?

• Very high, similar to crystalline solids

• Moderate, depending on the size of the solid

• Low, due to weak intermolecular forces

• Amorphous solids do not melt or boil
