Chemistry. Unit 5, Making molecules : Lewis Structures and molecular geometries / [produced by the Science Media Group at the Harvard-Smithsonian Center for Astrophysics]
Molecules can form when atoms bond together by sharing electrons and can be represented by a useful shorthand called Lewis Structures. These visual representations provide information to predict the three-dimensional shapes of molecules using valence shell electron pair repulsion ("VSEPR") theory. Understanding how atoms bond within molecules provides insight into cell replication. Building on this knowledge, the shapes of molecules reveal the effectiveness of important antibiotics such as penicillin, and scientists can manipulate shapes of molecules to help design new cancer-treating drugs
