Verified step by step guidance1
Identify the elements involved: lithium (Li) is a metal and bromine (Br) is a nonmetal.
Determine the charges of the ions formed: lithium typically forms a +1 cation (Li\^{+}), and bromine forms a -1 anion (Br\^{-}).
Combine the ions in a ratio that results in a neutral compound. Since both ions have charges of magnitude 1 but opposite signs, they combine in a 1:1 ratio.
Name the compound by stating the metal first (lithium) followed by the nonmetal with its ending changed to '-ide' (bromide).
Thus, the correct name of the ionic compound formed from lithium and bromine is lithium bromide.
