Vocabulary Terms

• Malleable- Metals are malleable, which means they
  can be hammered or rolled into sheets like
  aluminum

  copper

3
Terms cont.

• Metallic Bond- When metals bond with themselves
  or with other metals they do so with metallic
  bonds
• These electrons in metallic bonds move freely.
