according to dobereiner's traid the average atomic mass of traid is equal to the mass of the middle element's atomic mass so 23+7=30÷2=15approxx... remember to use approxx because the traid law is not gives you the exact value of atomic mass of the middle one bye i am also studying this chapter bye
