Step 2: Understanding the Chemical Structure
- Total valence electrons: $$6 + 1 = 7$$ electrons
The hydroxide ion (OH) has a specific electronic configuration that determines its charge. Let's break down the ion's composition: - Oxygen (O) has 6 valence electrons - Hydrogen (H) has 1 valence electron
Final Answer
Hydroxide is written as \mathrm{OH}^{-} because it gains 1 electron to complete its electron octet, resulting in a single negative charge.
