Multiple Choice

What are the four basic types of chemical bonds described in the lesson?

• Metallic, Network covalent, Molecular covalent, Ionic

• Hydrogen, Metallic, Ionic, Van der Waals

• Covalent, Ionic, Hydrogen, Metallic

• Network covalent, Ionic, Metallic, Polar

Use this simulation on the next slide to arrange the atoms so that they pack together in a continuous (unbroken) structure, called a crystal, as they form ions
