Draw a diagram of a carbon atom and label the locations of the 3 types of subatomic particles. 2. What are the 3 major types of chemical bonds? (Be sure you understand the differences between them.) Ionic, covalent, hydrogen 3. Draw a diagram of a water molecule. What makes water a polar molecule? Water is a polar molecule because oxygen attracts electrons more strongly than does hydrogen so the oxygen end of a water molecule is a slightly negative and each hydrogen is a slightly positive. 4. What do free radicals and antioxidants have to do with each other? Free radical is a molecule with...
