how was the work of newlands similar to that of mendeleev on the periodic table? o they both arranged the elements in order of increasing atomic mass. o they both arranged elements that had similar properties into groups. o they both predicted the positions of undiscovered elements on the table. o they both placed the relative atomic mass of each element on the table.
Answer
Brief Explanations:
Newlands and Mendeleev both arranged elements in order of increasing atomic mass. Newlands' Law of Octaves and Mendeleev's periodic table had this common - approach. While Mendeleev predicted positions of undiscovered elements and both grouped elements with similar properties, the most fundamental similarity was arranging by increasing atomic mass.
Answer:
They both arranged the elements in order of increasing atomic mass.
