Question

Dobereiner's Triads
In the year 1817 a German scientist Dobereiner suggested that properties of elements
are related to their atomic masses. He made groups of three elements each, having similar
an
chemical properties and called them triads. He arranged
the three elements in a triad in
was approximately equal to the mean of the atomic masses of the other two elements.
However, all the known elements could not be classified
into the Dobereiner's triads.
Create questions on this paragraph. And also write their answers​

Answer 1

Answer:

1. where do Dobereiner belongs to ?
2. Who made triads ?
3. What do you mean by triads ?
4. Which properties should be there to call triads ?
5. Did he classified all the known elements?
6. How to know whether they are triads or not ?

Explanation:

1. Dobereiner belongs to Germany .
2. Triads were made by Dobereiner ( German scientist )
3. groups of three elements each, having similar physical properties and chemical properties then they are called triads
4. • Same physical and chemical properties

• 3 elements in triad should be equal to the mean of the atomic masses of the other two elements

5. He didn't classified all the known elements

6.3 elements in triad should be equal to the mean of the atomic masses of the other two elements
