Step 2:: Identify the Ion
The problem asks about the iodide ion, which is represented by I^{-}. The negative sign indicates a negative charge.
Step 3:: Determine the Charge
The iodide ion (I^{-}) has a charge of - 1. This means the ion has gained one electron, resulting in a single negative charge.
Step 4:: Charge Origin
- Iodine's atomic number is 53 - In its neutral state, iodine has 53 protons and 53 electrons - When it becomes an ion, it gains one additional electron - This results in 54 electrons and still 53 protons - The extra electron creates the - 1 charge
Final Answer
The iodide ion I^{-} carries a - 1 charge.
