If so, you would potentially only have to use the scale 1 time to identify the heavier ball

Yes, 7 identical and 1 heavier but looks the same.

Okay then Steel's answer is correct.
But there is a possibility you can identify the heavier ball by using the scale only once if you happen to pick the heavier ball the first time and weigh it against one of the 7.
Potentially the answer is once

So it is possible to identify the heavier ball with a single weighing, though the probability is 1/4 (25% chance)
