In our life, we work almost exclusively with compounds. But a few objects are elements, such as iron. The biggest reason for this is elements tend to combine to form compounds. If the name is on the Periodic Table in one single box, it is an element. For example, Aluminum (Al) is an element while Table Salt (NaCl) is a compound. Which of the following is an element?

H₂0 (water), Calcium (Ca), or CO₂ (Carbon Dioxide)

• Contain atoms of different elements bonded together

• ​Can be broken down into simpler substances by chemical means (not physical).

• ​Have properties different than their component elements
