Solution
Solution Steps
Step 1: Understand the Charge of Chlorine Ion
Chlorine typically forms an ion with a charge of \(-1\). This is because chlorine is a halogen and needs to gain one electron to achieve a stable electron configuration similar to the noble gases.
Step 2: Identify Elements with Similar Electron Configurations
Elements that are likely to form ions with a \(-1\) charge are those that are in the same group as chlorine in the periodic table, specifically the halogens. These elements need to gain one electron to achieve a stable electron configuration.
Step 3: Analyze Each Element
I (Iodine): Iodine is a halogen, like chlorine, and typically forms an ion with a \(-1\) charge.
F (Fluorine): Fluorine is also a halogen and forms an ion with a \(-1\) charge.
Mg (Magnesium): Magnesium is an alkaline earth metal and typically forms a \(+2\) charge, not \(-1\).
K (Potassium): Potassium is an alkali metal and typically forms a \(+1\) charge, not \(-1\).
S (Sulfur): Sulfur is not a halogen, but it can form a \(-2\) charge, not \(-1\).
Final Answer
The elements that are likely to form ions with the same charge as chlorine (\(-1\)) are:
\[
\boxed{\text{I, F}}
\]
