Step 1:I'll solve this step-by-step:
Step 2:: Understand the Chemical Composition of a Hydroxide Ion
A hydroxide ion ($$\text{OH}^{-}$$) consists of one oxygen atom and one hydrogen atom.
Step 3:: Determine the Ionic Charge
- To balance the total charge, the ion must have a net charge of $$-1
- Hydrogen typically has a charge of + 1 in ionic compounds
Step 4:: Calculate the Total Charge
-2 + (+1) = -1
Step 5:: Verify the Charge
The hydroxide ion ($$\text{OH}^{-}$$) has a charge of $$1-$$.
Final Answer
Explanation: The hydroxide ion carries a single negative charge due to the way the oxygen and hydrogen atoms' charges combine. This makes option D (1 -) the correct answer.
