Question

you may want to reference (pages 169 - 174) section 4.6 while completing this problem. part a write the formula for the compound formed between cesium and chlorine. express your answer as a chemical formula.

Explanation:

Step1: Determine the ions formed

Cesium (Cs) is an alkali metal in group 1. It loses one electron to form \(Cs^+\) ion. Chlorine (Cl) is a halogen in group 17. It gains one electron to form \(Cl^-\) ion.

Step2: Write the formula

In an ionic compound, the charges must balance. Since the charge of \(Cs^+\) is \(+ 1\) and the charge of \(Cl^-\) is \(-1\), the formula is \(CsCl\) as the ratio of \(Cs^+\) to \(Cl^-\) is \(1:1\).

Answer:

\(CsCl\)
