Question

Which of the following is a Dobereiner’s triad.

Answer 1

Answer:

a) P(31),As(74.9),Sb(122) and (d) S(32),Se(79),Te(127.6) represent Dobereiners triad.

a) P(31),As(74.9),Sb(122) and (d) S(32),Se(79),Te(127.6) represent Dobereiners triad.In Dobereiners triad, the atomic weight of middle element is nearly the same as average of the atomic weights of other two elements.
