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 1/8
Right, but you have to be able to use the method consistently, as per the question. There are actually two ways to solve the problem, but they both equal 3 tries.
