Reaction of Group IA Metals with Group VIIA Nonmetals Formation of Ionic Compounds The underlying reason for the formation of LiF lies in the electron configurations of Li and F. 1s 2s 2p Li ¯ F ¯ ¯ ¯¯ These atoms form ions with these configurations . Li + ¯ same configuration as [He] F - ¯ ¯ ¯ ¯ ¯ same configuration as [Ne] Formation of Ionic Compounds We can also use Lewis dot formulas to represent the neutral atoms and the ions they form. Formation of Ionic Compounds The Li + ion contains two electrons, same as the helium atom.

Unformatted text preview: Li + ions are isoelectronic with helium. The F-ion contains ten electrons, same as the neon atom. F-ions are isoelectronic with neon. Isoelectronic species contain the same number of electrons. Formation of Ionic Compounds The reaction of potassium with bromine is another example of a group IA metal with a Group VIIA non metal. Write the reaction equation. You do it! Formation of Ionic Compounds...
