As per Dobereiner’s triad, the atomic mass of the middle element is the average of the atomic mass of first and third element.
Given,
Mass of A = 7
Mass of C = 39
Mass of B = (7+39)/2 = 23
A, B and C are the elements of a Dobereiner’s triad. If the atomic mass of A is 7 and that of C is 39, what should be the atomic mass of B?
