You may want to make a few changes before sharing this slide show with your chemistry class. For one, remove the bright blue swirly background that makes the black font hard to read. Ionic bonds are described with the use of an electron dot diagram. Covalent bonds are explained with the use of colorful diagrams displaying the electron shells. The link to the movie about covalent bonding does not work, so this is another issue that you may want to resolve prior to using the resource.
