Here are the different types of atoms displayed by using gumdrops, raisins, and toothpicks.
This is Phosphorus Pentafluoride. Also written as PF5. It has 40 valence electrons. This is Aluminum Hydride. Also written as AlH3. It has 6 valence electrons. This is Formaldehyde or Methanal. Also written as CH2O. It has 12 valence electrons. This is Carbon Disulfide. Also written as CS2. It has 16 valence electrons. This is Nitrogen Trifluoride. Also written as NF3. It has 26 valence electrons. This is Caffeine. Also written as C8H10N4O2. | This is Phosphorus Trihydride. Also written as PH3. It has 8 valence electrons. This is Sulfur Dioxide. Also written as SO2. It has 18 valence electrons. This is Sulfur Trioxide. Also written as SO3. It has 24 valence electrons. This is Ozone. Also written as O3. It has 18 valence electrons. This is Dihydrogen Sulfide. Also written as H2S. It has 8 valence electrons. This is Asprin. Also written as C9H8O4. |
This is Nicotine. Also written as C10H14N2.
My group and I worked together to complete this lab. We all chose a molecule and helped each other create it. The different gumdrop colors represent different elements in the particular molecule, the raisins represents the hydrogen atoms, and the toothpicks represent the bond. The first 10 molecules are inorganic compounds, and the remaining 3 are organic compounds.
I learned a lot through this lab about compounds and their structure. I already had an understanding of the Lewis Dot Structure, so knowing this helped a lot for creating the compounds. It was also very helpful to physically see how the atoms would look on a molecular scale.
It was interesting to see the structure and shape of the molecules because most of them varied differently from each other. And I noticed molecules that were contained similar elements also showed a similar structure, like SO2 and SO3.
These findings relate back to my last lab about smell. I concluded that similar smells also have similar structure, and for this lab I am concluding that similar molecule structures contain similar elements.
