GenChem - Chemical Bonding - Lecture

What is formed when oppositely charged ions attract each other?

• A) A covalent bond

• B) A metallic bond

• C) An electrically neutral ionic compound

• D) A polar molecule

How do ionic bonds form and how are the ions arranged in an ionic compound?

• By sharing electrons and arranged randomly

• By transferring electrons and arranged in a repeating pattern

• By transferring protons and arranged in layers

• By sharing protons and arranged in a crystal lattice

What can you conclude about the strength of ionic bonds based on the physical properties of ionic compounds?

• Ionic bonds are weak because ionic compounds have low melting points

• Ionic bonds are strong because ionic compounds have high melting points

• Ionic bonds are weak because ionic compounds are good conductors of electricity in solid state

• Ionic bonds are strong because ionic compounds are malleable
