– ANSWER KEY – Draw the 2-D LEWIS structure below the molecular formula. Determine both electron-domain (ED) and molecular geometry. Determine whether bond angles are ideal (90o, 109.5o, 120o, 180o) or distorted due to lone pair – bonding pair repulsion. elements or atoms. It is the combination of these atoms and molecules that result in the different substances. For example, sugar is also made up of hydrogen and oxygen, but adds a third element: carbon.
