The correct formula for the ionic compound containing Tl³⁺ and Te^2- ions would be

Question

Quizplus · Accepted Answer

In ionic compounds, the overall charge must balance out to zero. Therefore, the number of positive charges (cations) must equal the number of negative charges (anions). 
For TlS1U1P13+S1S1P0 and TeS1U1P12-S1S1P0, we can see that the cations are Tl and Te, while the anions are S1U1P13+S1S1P0 and S1U1P12-S1S1P0. 
To balance out the charges, we need one Tl ion to combine with one Te ion. Additionally, we need one S1U1P13+ ion to combine with one S1U1P12-S1 ion. Therefore, the correct formula would be TlS1U1B12S1U1B0TeS1U1B13S1U1B0, which is choice C.
