Dice that'll make you think. This version of a standard D6 Die has the name of each of the first 6 elements of the period table on the faces. You won't need to recall your chemistry lessons when you play with these as the faces show the atomic numbers for each element (how many protons the element has in the nucleus) represented as electrons orbiting the element symbol. For reference they are as follows: 1 - H (Hydrogen) 2 - He (Helium) 3 - Li (Lithium) 4 - Be (Beryllium) 5 - B (Boron) 6 - C (Carbon) Click my account to see other versions of these dice.
