Final answer:

Dmitri Mendeleev arranged the periodic table by atomic number, a departure from the previous practice of ordering by atomic mass, enabling the prediction of unknown elements.


Explanation:

Dmitri Mendeleev arranged the periodic table based on atomic number, not atomic mass, as was the common practice at the time. He had to list some elements out of order of their atomic masses to group them with similar properties. This organization allowed for predicting the properties of elements that had not yet been discovered, showcasing the power of Mendeleev's arrangement.
