Exploring Molecular Shapes
1. The question we had in this lab was, How does the number of things around the central atom affect the shape of a molecule? We wanted to answer this because not all molecules have the same shape. 2. During our experiment we checked how the shape of molecules changed when we added bonding pairs or lone pair electrons. We noticed that when we added a another bonding pair to the molecule the angles between the pairs decreased. The less bonding pairs they had, the bigger the angles would be. 3. So our claim ended up being " The number of things around a central atom changes the shape of the molecule because of vesper".Our evidence came up with how many bonding pairs we put on a molecule as well as lone pair electrons. With two bonding pairs the angle would be 180 degrees. Add one more and it would go to 120, 4 bonding pairs and it makes 109 degrees, 5 bonding pairs and it would be 90 degrees, and lastly bonding pairs make it go to 90 degrees. In the other hand adding mo
