Valence Electrons and Lewis Structures

Dr. B explains how to draw the Lewis structure for CH3Cl. The process involves counting valence electrons for carbon, hydrogen, and chlorine, positioning the atoms with carbon in the center, and forming chemical bonds. The video ensures each atom achieves a full outer shell, completing the structure with 14 valence electrons.

Does each atom in CH3Cl have a full outer shell in the completed Lewis structure?

• Yes, all atoms have full outer shells.

• No, only Carbon and Chlorine have full outer shells.

• No, only Hydrogen has a full outer shell.

• No, none of the atoms have full outer shells.
