July 6, 2017Lab Experiment #2: Introduction to MoleculesLab Partners: N/AIntroduction to Molecules
Purpose & HypothesisThe purpose of this lab is to create molecules and to study how they bond. My hypothesis for thislab is if I complete all the activities of drawing and creating structure, then I will betterunderstand their polarity and how molecules bond.Pre-Lab Questions:1Most elements exist as components of compounds rather than in a free state. Explain why.
2Use colored pencils to lightly shade each element in the Periodic Table of ElectronegativityValues.Color 1Color 2Color 3Color 40 – 0.91.0 – 1.92.0 – 2.93.0 – 4.0DataData Table 1 (Make Copies of This Table)
