The predicted atomic mass of K from the atomic masses of Na and Rb with the use of Dobereiner’s triads is to be determined. Concept introduction: Dobereiner stated that all elements occur in the groups of three when arranged in the increasing order of their atomic masses. Such groups of three elements were called triads which have similar chemical properties. The triads can be used to calculate the atomic mass of the middle element by the average of the elements which lie above and below the given element.
