Families of Elements Kit

SCIENTIFIC CONCEPTS / PROCESSES

• Learn to classify elements by observing behavior of their compounds
• Examine properties of the halogen compounds
• Determine formulas of compounds through experimentation

Students learn how to classify elements by observing the behavior of compounds in the Halogen Family (Group VIIA). The chemical properties of this group are very similar despite the marked differences in their physical properties.

As students perform a series of experiments, they discover that the elements form remarkably similar compounds with silver. Also, that the formulas of the compounds are similar, and that the elements are indeed in the same family.

The methods used in this kit for determining chemical formulas are also used in the Determination of Chemical Formulas Kit (LA85).
