Question

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

Answer 1

Answer:

Doberniars triads are group of three elements in which the average of atomic mass of 2 elements is is equal to the the atomic mass of third element that is the middle element.

Doberniars triads are group of three elements in which the average of atomic mass of 2 elements is is equal to the the atomic mass of third element that is the middle element.so,( 35.5+127)÷2=80(approx).

so, the three elements form a triad

Answer 2

Answer:

Atomic mass of chlorine is 35.5

Atomic mass of bromine is 80

Atomic mass of iodine is 127

When we add atomic mass of chlorine and iodine and divide it by 2= 35.5+127/2

It gives 81.25 which is closer to atomic mass of bromine
