how was the work of newlands similar to that of mendeleev on the periodic table? they both arranged the elements in order of increasing atomic mass. they both arranged elements that had similar properties into groups. they both predicted the positions of undiscovered elements on the table. they both placed the relative atomic mass of each element on the table.

Explanation:

Newlands and Mendeleev both arranged elements in order of increasing atomic mass while constructing the periodic table. Newlands' Law of Octaves and Mendeleev's periodic table were early attempts at organizing elements. Arranging by atomic mass was a common approach at that time.

Answer:

They both arranged the elements in order of increasing atomic mass.
