5.Dobereiner's Triads classify elements based on a specific pattern in their atomic weights. Which of the following correctly describes Dobereiner's Triads with an example?
- A.Elements are grouped in triads where the atomic weight of the middle element is the arithmetic mean of the other two. Example: Calcium (40), Strontium (88), Barium (137).
