LiCl
B
LF
C
LiO
D
LiF
Verified step by step guidance
1
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 these elements. 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 the cation (Li) first followed by the anion (F), resulting in LiF.
Step 5: Verify that the formula represents a neutral compound by ensuring the total positive and negative charges balance out.
