### Lithium Atom and Ion Transformation #### Explanation: When a lithium (Li) atom becomes a Li⁺ ion, it loses one electron from its outer shell. This process decreases its atomic radius. #### Diagrams: - **Li Atom (radius = 152 pm):** - The depiction shows a lithium atom with its electrons and a radius of 152 picometers (pm). - **Li⁺ Ion (radius = 90 pm):** - After losing one electron, the ion's new radius is reduced to 90 pm. #### Electron Configuration Change: - **Before Ionization:** - Electron configuration: 1s² 2s¹ - **After Ionization:** - Electron configuration becomes: 1s² ### Fluorine Atom and Ion Transformation #### Explanation: When a fluorine (F) atom becomes an F⁻ ion, it gains one electron, resulting in an increase in its atomic radius. #### Diagrams: - **F Atom (radius = 72 pm):** - Shows a fluorine atom with a radius of 72 picometers (pm). - **F⁻ Ion (radius = 119 pm):** - After gaining an electron, the ion's radius increases to 119 pm. #### Electron Configuration Change: - **Before Ionization:** - Electron configuration: 1s² 2s² 2p⁵ - **After Ionization:** - Electron configuration becomes: 1s² 2s² 2p⁶ These visualizations and explanations help to understand the changes in atomic structure and size when lithium and fluorine atoms transform into their respective ions.
