Unformatted text preview: as shown in , lithium can achieve a noble gas configuration, 1s 2 , by donating an electron to fluorine which also achieves the noble gas configuration 1s 2 2s 2 2p 6 : Figure %: Transferring an electron from Li to F gives both noble gas electron configurations. The above reaction represents the formation of an ionic bond. The negatively charged anion, F, and the positively charged cation are held together in the bond by the attraction of unlike charges as dictated by Coulomb's law. You may have asked yourself why two fluorine atoms don't come together to perform the following reaction: Even though the reaction may appear to be favorable because of its production of a closed shell species, there is a way to have both F atoms achieve a noble gas configuration. By sharing their electrons, each fluorine atoms can have a complete octet in its valence shell....
