Lithium fluoride is used as a flux in the production of ceramics and glazes. Given their location on the periodic table, identify the ionic charge for each element and predict the chemical formula of the compound formed. A) Lithium, Li, is an alkali metal and is in Group IA with an ionic charge of +1. While fluorine, F, is a halogen and is in Group VIIA with a charge of -1. These will form LiF(s). B) Lithium, Li, is an alkaline earth metal and is in Group IA with an ionic charge of +2. While fluorine, F, is a halogen and is in Group VIIA with a charge of -1. These will form LiF2(s). C) Lithium, Li, is an alkaline earth metal and is in Group IA with an ionic charge of +2. While fluorine, F, is a noble gas and is in Group VIA with a charge of -2. These will form Li2F2(s). D) Lithium, Li, is an alkaline earth metal and is in Group IA with an ionic charge of +1. While fluorine, F, is a diatomic gas and is in Group VIA with a charge of -2. These will form Li2F(s).
