Question

write the charge of each ion in the compound below.
lioh
li =
oh =
write the name for the formula below.

Explanation:

Step1: Determine the charge of Li ion

Li is in group 1 of the periodic table. Elements in group 1 have a tendency to lose one electron. So, the charge of Li ion ($Li^{+}$) is $+ 1$.

Step2: Determine the charge of OH ion

The hydroxide ion ($OH^{-}$) is a polyatomic ion. By common knowledge of polyatomic ions, the charge of the hydroxide ion is $-1$.

Answer:

$Li = +1$; $OH=-1$; The name of $LiOH$ is lithium hydroxide.
