I had to have some help.
I made sure that before I clicked on "next task" after getting into the
monorail station, I walked in close to the left side of the the desk.
I waited for a monorail to come and leave, so when I clicked for the first
atom, I had TIME to walk near the left monorail queue side.
Be sure to click the desk, walking alongside it.
That's how I got my first atom.
Second atom is the bottom left corner by the fence.
Third atom is on a chair.
Fourth atom is hidden near the fence BETWEEN the sets of chairs.
And Fifth atom is out in the open.
