Think about the fact that, even if you fill up all elements to maximum capacity, you'll have a little more than the number of molecules present in one gram of hydrogen gas.
When you are doing the puzzles, some groups disappear altogether. This makes some combinations impossible to make, making the puzzle unwinnable. I can't even find elements I already created on the alphabetic list.
