Understand that the question is about the historical development of the periodic table and who arranged the elements by atomic mass.
Recall that Dmitri Mendeleev is credited with creating the first widely recognized periodic table, where he arranged elements in order of increasing atomic mass.
Note that Marie Curie is known for her work on radioactivity, not for arranging the periodic table.
Recognize that Henry Moseley later refined the periodic table by arranging elements according to atomic number, not atomic mass.
Remember that John Dalton is famous for atomic theory but did not arrange the periodic table.
