Question
fill in the name and empirical formula of each ionic compound that could be formed from the ions in this table: some ionic compounds (table with cation cs⁺, anions i⁻, cl⁻, br⁻, f⁻, columns for empirical formula and name of compound)
Step1: Determine the empirical formula (Cs⁺ and I⁻)
The cation is \( \text{Cs}^+ \) (charge +1) and the anion is \( \text{I}^- \) (charge -1). To balance the charges, we need 1 \( \text{Cs}^+ \) and 1 \( \text{I}^- \), so the empirical formula is \( \text{CsI} \).
Step2: Name the compound (CsI)
The cation is cesium (\( \text{Cs}^+ \)) and the anion is iodide (\( \text{I}^- \)), so the name is cesium iodide.
Step3: Determine the empirical formula (Cs⁺ and Cl⁻)
The cation is \( \text{Cs}^+ \) (charge +1) and the anion is \( \text{Cl}^- \) (charge -1). To balance the charges, we need 1 \( \text{Cs}^+ \) and 1 \( \text{Cl}^- \), so the empirical formula is \( \text{CsCl} \).
Step4: Name the compound (CsCl)
The cation is cesium (\( \text{Cs}^+ \)) and the anion is chloride (\( \text{Cl}^- \)), so the name is cesium chloride.
Step5: Determine the empirical formula (Cs⁺ and Br⁻)
The cation is \( \text{Cs}^+ \) (charge +1) and the anion is \( \text{Br}^- \) (charge -1). To balance the charges, we need 1 \( \text{Cs}^+ \) and 1 \( \text{Br}^- \), so the empirical formula is \( \text{CsBr} \).
Step6: Name the compound (CsBr)
The cation is cesium (\( \text{Cs}^+ \)) and the anion is bromide (\( \text{Br}^- \)), so the name is cesium bromide.
Step7: Determine the empirical formula (Cs⁺ and F⁻)
The cation is \( \text{Cs}^+ \) (charge +1) and the anion is \( \text{F}^- \) (charge -1). To balance the charges, we need 1 \( \text{Cs}^+ \) and 1 \( \text{F}^- \), so the empirical formula is \( \text{CsF} \).
Step8: Name the compound (CsF)
The cation is cesium (\( \text{Cs}^+ \)) and the anion is fluoride (\( \text{F}^- \)), so the name is cesium fluoride.
