1 CHAPTER 3: Part 3 Lewis Structures

2 LEWIS STRUCTURES (1) We have been drawing Lewis Structures like H-H or H-Cl. These diagrams show the atoms, the chemical bonds and the nonbonding ve's. CH 4 : C has 4 ve's and each H atoms has one ve. The Lewis structure shows four C-H covalent bonds http://www.chembio.uoguelph.ca/educmat/ chm19104/vsepr/index.htm
