2.4 Simple and Giant Structure

What is an ionic compound?

• A compound formed by sharing electrons

• A compound formed by transferring electrons

• A simple molecule

• A giant covalent structure

What type of bond holds ions together in an ionic compound?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

What is the arrangement of ions in a sodium chloride crystal?

• Random

• Regular pattern

• Linear chain

• Network structure

Why do ionic compounds have a regular shape?

• Due to the size of the ions

• Due to the arrangement of the ions

• Due to the type of bond

• Due to the intermolecular forces

What is a giant covalent structure?

• A simple molecule

• A large molecule formed by many covalent bonds

• An ionic compound

• A metallic structure

What is the difference between a simple molecular substance and a giant covalent structure?

• The type of bond

• The size of the molecule

• The intermolecular forces

• All of the above

What is the type of bond between carbon atoms in diamond?

• Ionic bond

• Covalent bond

• Metallic bond

Why is diamond so hard?

• Due to the strong covalent bonds between carbon atoms

• Due to its high melting point

• Due to its crystalline structure

• Due to its electrical conductivity

What is the main use of diamond?

• Jewelry

• Cutting and drilling tools

• Electrical conductor

• Lubricant

What is the structure of graphite?

• A network of carbon atoms arranged in layers

• A simple molecule

• An ionic lattice

• A metallic structure
