1) What is the chemical formula for the compound formed between thallium(iii) and bromine?
2) What is the chemical formula for the compound formed between thallium(iii) and sulfur?
HINT!: each compound wil be neutral. What is the charge of the thallium(iii) ion? What is the charge of the most common ion formed by bromine and sulfur?

The easy way to do these is to write (ignore the dots--I must do that for spacing) the symbols.
Then write above the symbols the valence. For Tl that is +3 (the III tells you that and for Br it is -1.
Now make a big X through that dot in the middle between Tl and Br. The top left of the X is the +3, bring it down to the bottom right on Br. The 1 (ignore the - sign) at the top right for over Br; bring that down to the bottom left of the X So te formula is
Do the same for Tl and S. Use +3 for Tl and -2 for S.
