(a)
Interpretation: The formula of ionic compound formed from
Concept Introduction: Ionic compounds are formed by the chemical combination of a metal and a non-metal. Here, metals tend to be electron-rich; thus, they lose electron/s to form a cation. Similarly, non-metals tend to be electron deficient, thus, they gain electron/s to form an anion. These cations and anions can combine in a fixed ratio to form ionic compounds.
(a)
Explanation of Solution
The given ions are
Since ionic compounds are electrically neutral (charge zero), thus, Ba and Br ions combine in such a way that the total charge of the compound is 0.
Here, Ba and Br ions combine in a 1:2 ratio to form
(b)

(b)
Explanation of Solution
The given ions are
Since ionic compounds are electrically neutral (charge zero), thus, Al and S ions combine in such a way that the total charge of the compound is 0.
Here, Al and S ions combine in a 2:3 ratio to form

(c)
Explanation of Solution
The given ions are
Since ionic compounds are electrically neutral (charge zero) thus, K and N ions combine in such a way that the total charge of the compound is 0.
Here, K and N ions combine in a 3:1 ratio to form
