Mebdeleev's classification was a great improvement over contemporary tabulation of the elements by Newlands and Lothar Meyer because  (i) it grouped the elements together more accurately in vertical columns. (ii) it left gaps for elements which were yet to be discovered in nature. (iii) it made possible the predication of the properties of elements that had not yet been discovered. (iv) it predicted that atomic masses of certain elements were incorrectely determined.
