Question

show that the chlorine bromine and iodine atomic mass 35.5,80 and 127 respectively constitute a triad​

Answer 1

Answer: According to Dobereiner's Triads Chlorine, Bromine and Iodine forms triad.

Explanation: Atomic mass of Chlorine : 35.5

                      Atomic mass of Bromine : 80

                    Atomic mass of Iodine : 127  

 Atomic mass of Chlorine + Atomic mass of Iodine /2

= 35.5 + 127 /2

= 162.5 / 2

= 80 (approx.)

= Atomic mass of Bromine

Hence Proved
