Atomic Puzzle

Your task in this nice original puzzler is to remove atoms in the right order and predicting the merging of the molecules so that there's none left at the end of each level. Remove all the balls from the screen by "crashing" them into each other. Use YOUR MOUSE and click on an atom that is attached to two or more of the same color to collide them together. Continue to combine the colors until there is nothing left on the screen. Good luck!
