Verified step by step guidance1
Understand that lithium hydroxide is a compound made of lithium ions and hydroxide ions.
Recall that lithium (Li) typically forms a +1 charge as a cation (Li⁺).
Recognize that the hydroxide ion (OH) carries a -1 charge.
Since lithium has a +1 charge and hydroxide has a -1 charge, they combine in a 1:1 ratio to balance the charges.
Write the chemical formula by placing Li and OH together without any additional subscripts, resulting in \(LiOH\).
