Explanation:

Proposed Arrangement:
- Dmitri Mendeleev and Lothar Meyer proposed arranging elements in increasing order of their atomic weights.

Reasoning:
- The periodic table was initially arranged based on increasing atomic weights of elements.
- Mendeleev noticed that when elements were arranged in this order, there was a periodic repetition of properties.
- This led to the development of the periodic law and the modern periodic table.

Significance:
- The arrangement of elements in increasing atomic weights allowed for the prediction of properties of undiscovered elements.
- Gaps in the table could be filled with elements that were later discovered and found to fit the predicted properties.

Contribution:
- Mendeleev's periodic table laid the foundation for the modern periodic table we use today.
- The periodic table arranged by atomic weight was a significant advancement in the field of chemistry.
