Final answer:
The Lewis structure of the hydroxide ion (OH⁻) consists of the oxygen atom bonded to a hydrogen atom. The total number of valence electrons in the hydroxide ion is 8.
Step-by-step explanation:
The Lewis structure of the hydroxide ion (OH⁻) consists of the oxygen atom bonded to a hydrogen atom. The total number of valence electrons in the hydroxide ion is 8. To represent the ion with a negative charge, we add an extra electron to the central atom. So, we need to show 8 electrons in the Lewis structure of the hydroxide ion.
