**SCIENTIFIC QUESTION:**  
*Why are compounds composed of integer ratios of elements?*

On page four paragraph one it says, “we need to place parentheses around the ion’s formula before using a subscript to indicate how many ions of that type are in the compound.” The formulas of compounds must be an integer value as these integer values describe the charges on the ions, and charges originate from the loss or gain of electrons.
