Your question isn't clear. Please clarify it; it appears you have typed only a part and expect us to know the remainder.

whoops

Write a formula for the ionic compound that forms between each of the following pairs of elements

ZnS. They want the formula of the compound. Your previous response gave the ions of the compound which is why you obtained the formatting answer.

thank you so much you are awesome. ;-)

To correctly express Zinc (Zn) and Sulfur (S) as a chemical formula, you need to consider their respective charges. Zinc typically forms a 2+ cation (Zn2+), while sulfur typically forms a 2- anion (S2-).

To combine these elements and balance their charges, we need to use the crisscross method. This method involves crossing the numerical values of the charges and placing them as subscripts. Here's how you can do it:

1. Identify the charges of each element: Zn2+ and S2-
2. Crisscross the charges and place them as subscripts: Zn2+ S2- becomes ZnS2.
3. Simplify the formula (if possible): Since the subscript of Sulfur is 2, it indicates that there are two sulfur atoms present. However, for simplicity, we usually write the formula without the subscript 1. Therefore, the final chemical formula is ZnS.

So, the correct chemical formula for Zinc and Sulfur is ZnS.
