Step 1:I'll solve this problem step by step:
Step 2:: Understand the Periodic Table Location
Iodine (I) is located in Group 17 (the halogen group) on the periodic table. Halogens typically form negative ions by gaining electrons to achieve a stable electron configuration.
Step 3:: Determine Electron Configuration
Iodine's electron configuration is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{10} 4p^{6} 5s^{2} 4d^{10} 5p^{5}
Step 4:: Calculate Electron Gain to Achieve Stability
To achieve a stable electron configuration, iodine needs to gain one electron to complete its outer shell (5p orbital).
Step 5:: Determine Ion Charge
I + e^{-} \rightarrow I^{-}
When iodine gains one electron, it forms a - 1 charge:
Step 6:: Verify the Answer
This means iodine most commonly forms the $$I^{-}$$ (iodide) ion with a -1 charge.
Final Answer
The most common ion charge for iodine is - 1, which corresponds to option C.
