G.C.1-10 Lab Report Name: Nikky Marta Z Number: Z23528931 Summary of the Video: Throughout the history of chemistry, there have been several methods when it came to creating three dimensional models based off chemical atoms and bonds. Today, we use the ball and stick model in most situations, where the ball is the atom, and the stick represents the bond. For example, to make methane (CH4) you would attach four sticks to one ball. There are other ways to simulate different compounds such as using flexible sticks to create double or triple bonds. In terms of past theories, Van’t Hoff used paper pyramids to demonstrate the naturally tetrahedral shape of carbon- carbon bonds. However, these are not true today, as Pauling created a new hydrogenation theory, which had a more in-depth interpretation of hybridizations and used a more cohesive method of demonstrating these bonds by using wireframes. When making molecular models, you need to use the wood stick to connect the atoms. You also need to use different colors to distinguish when element is being used. For an example, if you are modeling CH4 then the C must be the biggest ball and must be black to represent the central atom. The H must be smaller and white to represent the atoms surrounding the central atoms. When connecting atoms with a double bond in a molecular model, you must use the spring to connect the atoms being bonded to represent the double bond and still use the wood stick to represent the single bonds. When connecting atoms, you must make sure that it is equal distance all around. 1
