Dobereiner noticed a relationship between the atomic masses of the elements in each triad
. Dobereiner arranged them by their atomic mass in groups of three. Thus the atomic masses give the arithmetic means that corresponds to 23. He observed that …

Quick Reference. One such triad was lithium, sodium, and potassium.
This was known as Dobereiner’s triad. The middle element, selenium, has an atomic mass that is close to the sum of the atomic masses of sulfur and tellurium, divided by 2. One such triad was lithium, sodium, and potassium. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. The atomic mass of the middle element of the triad is equal to the mean of the atomic masses of the other two elements of the triad.
