Argumentation and Documentation Classify each substance as metallic, ionic, molecular or covalent network based on your experimental results and further observations Part I. Testing Conductivity of Substances at Room Temperature Two substances were electrically conducting solids. The only classifications for substances that conduct electricity as solids are metallic or covalent network solids. Use the malleability property of metals to determine the classification of the two substances. Part II. Testing Conductivity of Solutions...
