Answer 1

Answer:

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{answer}}}}}}$

The Dobereiners law stated that the average of the sum of the atomic masses of first and third atom would be almost equal to the second one...

It's limitation was that he could only make 3 triards and Atomic Mass should not have been taken as the basis of classification...

Answer 2

Explanation:. Dobereiner noticed a pattern with certain elements that had similar chemical and physical properties. He called these elements triads and, thus, we have Dobereiner's Law of Triads. If you put these elements in order of their atomic masses, the average of the molar mass of the first and third elements in the triad is the molar mass of the second element. Let's look at an example.

The halogens, chlorine, bromine, and iodine, have atomic masses ≈ 35 g/mole, ≈ 80 g/mole, and ≈ 127 g/mole respectively. These values are rounded to the nearest g/mole. If we take the average of the masses of chlorine and iodine we get:

1/2(35 g/mole + 127 g/mole) = 81 g/mole, which is very close to bromine's atomic mass of 80 g/mole.
