Interpretation: The formula forthe ionic compound formed between calcium cations and chloride anions needs to be determined.
Concept Introduction: Ionic compound is formed by the chemical combination of a metal and a non-metal. Here, metal tends to be electron-rich, and non-metal tends to be electron deficient. Thus, metals donate electron/s to form a positively charged ion or cation and non-metals accept electron/s to form a negatively charged ion or anion. Here, ions of metal and non-metal combine in a fixed ratio to form an ionic compound such that the total charge is zero.
Answer to Problem 11SP
Explanation of Solution
The given cation and anion are calcium and chloride ions respectively. Here, calcium is metal and belongs to group 2. It has 2 valance electrons which can be donated to form calcium cation or
