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.
(b)

The predicted melting point of
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.
The triads can be used to predict the chemical properties of the elements.such as melting and boiling points. According to Dobereiner the boiling or melting point of the middle element can be calculated by taking the average of the first and third element in a given triad.
