Explanation:
) The average atomic mass of elements A and C =
2
7+39
=
2
46
=23
(b) The average atomic mass of elements A and C is the same as the atomic mass of element B=23.
(c) The element A is Lithium (Li), B is Sodium (Na) and C is Potassium (K). They are Dobereiner's Triads because in Dobereiner's Triads the atomic mass of the middle element is approximately the mean of the atomic masses of other two elements.
