Question

Give one similarity between Dobereiner's triads and Newland's law of octaves.

Answer 1

Part 1: Dobereiner’s triads:

• In Dobereiner's triads, the elements are arranged in the increasing order of their atomic masses.
• The atomic mass of the middle element is almost equal to the average mass of the other two elements.

Part 2: Newland’s law of octaves:

• According to Newland's law of octaves, the elements are also arranged in terms of their increasing atomic masses.
• This law states that the property of every eighth element is similar to that of the first element.

Part 3: Similarity between Dobereiner's triads and Newland's law of octaves:

Both Dobereiner's triads and Newland's law of octaves consider the same criteria for arranging the elements i.e., according to the increasing order of the atomic masses of the elements.
