Why are elements on the periodic table not arranged by mass? (1 point) This would not allow all of the elements with similar properties to be lined up with each other. This would not allow all of the elements with similar properties to be lined up with each other. Atoms are so small that it would make little sense to talk about their mass. Atoms are so small that it would make little sense to talk about their mass. Atoms with similar masses are so different from each other that this would lead to a random arrangement of atoms. Atoms with similar masses are so different from each other that this would lead to a random arrangement of atoms. Similar elements have such different masses that this would lead to a completely random arrangement of elements.
