Types of Chemical Bonds and Stability

Mr. Emil Vijandre introduces atomic bonding, focusing on covalent and ionic bonds. Covalent bonds involve sharing electron pairs between non-metals, following the octet rule for stability. Examples include chlorine, sulfur, and oxygen. Ionic bonds involve transferring electrons between metals and non-metals, such as sodium and fluorine, resulting in charged ions. The lesson concludes with a summary and farewell.
