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 cation anion empirical formula name of compound cs⁺ i⁻ cs⁺ f⁻ cs⁺ br⁻ cs⁺ cl⁻

Explanation:

Step1: Combine ions

For ionic compounds, the cation ($Cs^+$) and anion combine in a ratio to make the compound electrically - neutral. Since $Cs^+$ has a + 1 charge and each of the anions ($I^-$, $F^-$, $Br^-$, $Cl^-$) has a - 1 charge, the ratio of cation to anion is 1:1.

Step2: Name the compounds

The naming of ionic compounds follows the rule of naming the cation first and then the anion with the suffix '-ide'.

Answer:

cation	anion	empirical formula	name of compound
$Cs^+$	$F^-$	$CsF$	cesium fluoride
$Cs^+$	$Br^-$	$CsBr$	cesium bromide
$Cs^+$	$Cl^-$	$CsCl$	cesium chloride
