the correct formula for the ionic compound containing Tl^3+ and Te^2- ions would be:
Please show. thank you
Did you finish your post? I would write for this particular compound Tl2Te3 which I would name thalium(III) telluride
To determine the correct formula for an ionic compound containing Tl^3+ and Te^2- ions, we need to balance the charges of the ions so that they cancel each other out.
The charge of Tl^3+ indicates that thallium (Tl) has a positive charge of +3. The charge of Te^2- indicates that tellurium (Te) has a negative charge of -2.
Since the charges must balance, we need three Te^2- ions to balance out the charge of one Tl^3+ ion. This means we use a subscript of 3 for tellurium, and no subscript for thallium since it is only one.
Therefore, the formula for the ionic compound containing Tl^3+ and Te^2- ions is TlTe3.
Please note that when writing the formula, we do not include the charges as subscripts. The charges are only used to determine how many of each ion we need.
