During this lab, we used a combination of gumdrops, raisins, and toothpicks to create molecules. We chose 10 different molecules to draw its Lewis dot structures, showing our understanding of molecules. After the worksheet, we physically created the molecules by using the gumdrops as the main atoms (different colors meaning different elements), raisins as hydrogen, and toothpicks are bonds. We essentially learned the Lewis dot structure and how precise it has to be to get all 8 valence electrons. To have 8 valence electrons is called the octet rule. The octet rule is a chemical rule of thumb that states that atoms of elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. The shapes of the inorganic compounds and organic molecules had a specific patterns they followed. The shapes of the inorganic compounds seemed to have one element in the middle and the other elements surrounded it, whereas the organic molecules first formed a hexagon and was based off of that.
