Solution

Solution Steps

Step 1: Identify the Elements and Their Positions in the Periodic Table

Cesium (Cs) is an alkali metal located in Group 1 of the periodic table, which means it has one valence electron. Chlorine (Cl) is a halogen located in Group 17, which means it has seven valence electrons.

Step 2: Determine the Common Ionic Charges

Alkali metals, such as cesium, typically lose one electron to form a cation with a +1 charge ($\mathrm{Cs}^+$). Halogens, such as chlorine, typically gain one electron to form an anion with a -1 charge ($\mathrm{Cl}^-$).

Step 3: Predict the Compound Formed

When cesium ($\mathrm{Cs}^+$) and chlorine ($\mathrm{Cl}^-$) react, they combine in a 1:1 ratio to form an ionic compound. The resulting compound is cesium chloride (CsCl).

Final Answer

\[ \boxed{\text{b) CsCl}} \]
