explanation/justification.)

(Complete sentences required for explanations.)
Lab 1:
Describe and explain the behavior observed in metals. Use a drawing to aid in your
explanation.
What type of bond is involved in metals? _________________________________________________
Would the same behavior be seen in non-metals? Explain why or why not. Use a
drawing to aid in your explanation.
What type of bond is involved in non-metals? ____________________________________________
Describe and explain the two types of behavior observed in compounds. Use
drawings to aid in your explanation.
Make sure to identify the type of bond involved in both groups of compounds.
Lab 2:
Develop a set of “Rules for Identification” of the 3 groups of solid substances.
(Your rules must allow for correct classification of any substance. Identify the types of particles involved. Complete sentences
required.)
