What type of bond involves the sharing of electrons between non-metals?

• Ionic bond

• Covalent bond

• Hydrogen bond

• Metallic bond

What are simple molecular substances?

• Substances with ionic bonds

• Metals with free electrons

• Substances with giant covalent structures

• Small molecules with covalent bonds

Which of the following is an example of a giant covalent structure?

• Chlorine

• Water

• Ammonia (NH3)

• Diamond

What is required to melt or boil simple molecular substances?

• Breaking strong covalent bonds

• Breaking weak intermolecular forces

• Breaking ionic bonds

• Breaking metallic bonds

Why do simple molecular substances have low melting and boiling points?

• Because they are metals

• Because they have free electrons

• Because they have weak intermolecular forces

• Because they have strong covalent bonds

What happens to the boiling points of halogens as you go down the group?

• They stay the same

• They decrease

• They fluctuate

• They increase

Why do giant covalent structures have high melting and boiling points?

• Because they have strong covalent bonds

• Because they have strong ionic bonds

• Because they have weak intermolecular forces

• Because they have free electrons
