This Periodic table game helps you learn the group wise placement of all elements in the periodic table. The game play is same as the popular game - Ball Sort, but instead of sorting balls based on color you have to sort the elements based on the Group of periodic table that they belong to. For example, all elements of Group 1, i.e. H, Li, Na, K, Rb have to be sorted into one test tube and all elements of Group 2, i.e. Be, Mg, Ca, Sr, Ba have to be sorted in the other test tube. Click on a tube to select the uppermost element and transfer to a tube containing elements from the same group. 10 points will be added to your score for correct sorting of each group of elements. Your score will be deducted if an element is placed into an incorrect group of elements. Master the Periodic table by playing all 100 levels. There is no time limit for the levels so you can learn at your own pace. No boring ads to distract you from learning and enjoying the game.
