Question

1. what is the formula for lithium bromide lbr libr li₂br libr₂

Explanation:

Lithium bromide is an ionic compound. Lithium (\(Li\)) has a +1 charge (\(Li^{+}\)) and bromide (\(Br\)) has a -1 charge (\(Br^{-}\)). In ionic compounds, the charges of the ions must balance. Since the charges of \(Li^{+}\) and \(Br^{-}\) are equal in magnitude (1) and opposite in sign, the formula is \(LiBr\) (one \(Li^{+}\) and one \(Br^{-}\) to balance the charges).

Answer:

LiBr
