Verified step by step guidance

Step 1: Identify the elements involved. Lithium fluoride is composed of lithium (Li) and fluorine (F).

Step 2: Determine the charges of the ions formed by each element. Lithium typically forms a +1 ion (Li\^{+}), and fluorine forms a -1 ion (F\^{-}).

Step 3: Combine the ions in a ratio that results in a neutral compound. Since both ions have charges of equal magnitude but opposite sign, they combine in a 1:1 ratio.

Step 4: Write the chemical formula by placing the symbols of the elements together, with subscripts indicating the number of atoms if more than one is needed. Here, since the ratio is 1:1, no subscripts are needed.

Step 5: Conclude that the correct chemical formula for lithium fluoride is LiF.
