Periodic Table Clock & Dish
We can read the time on a clock. In a similar way people could know the atomic numbers. For example, phosphorus which is quarter past the hour is atomic number 15 and rhenium which is same place is 60+15 so its atomic number 75. Each symbol of element is placed on the outer side of each electron configuration. The number of electron configuration should be read according to the INDEX. Each group of elements is sorted by each symbol color. The six circles in the center symbolize a geologist and five chemists.
