Scientific question:
Why are compounds composed of integer ratios of elements? If the charges are not balanced it cannot be correct which is what we see in the image attached. Charges must be neutral/zero.
The image in itself will help answer the question above.
Note: You're answering the question above not the question in the image attached.
