Interpretation:
The formula unit of the compound formed from Ion ‘X’ having +2 charges and Ion ‘Y’ having -1 charge.
Concept introduction:
The atoms lose electrons or gain electrons to form ion. Based on the number of atoms present in the ions it is monatomic or polyatomic. Both of these carry charges and can be cation or anion. Both of these forms ionic compounds due to electrostatic forces of attraction between the oppositely charged ions.
Answer to Problem 36SSC
The formula unit of the compound formed from Ion ‘X’ having +2 charges and Ion ‘Y’ having -1 charge is
Explanation of Solution
The given ion is ‘X’ having +2 charges and ‘Y’ having -1 charge.
As ‘X’ having a charge of +2 would have been formed by losing two electrons and ‘Y’ would have been formed by gaining one electron, the formation of compound is depicted
Figure 1
Hence, the compound formed is
The formula unit of the compound formed from Ion ‘X’ having +2 charges and Ion ‘Y’ having -1 charge is
