The  Atlas badge is the most changeable of badges, always moving out of reach (except for the one time  Ben Eater, lead exercise developer on Khan Academy got it by mistake). It was once for completing 150 exercises, then 250 and then 500. Now it has changed again, to another unattainable number. I suspect that when Khan Academy feels there are enough exercises to cover all of high school maths (or maybe one topic), then they will settle on a number. But for now it is not possible.
