In 3-4 sentences describe how mendeleev's periodic table differs from moseley's

The primary difference between Mendeleev's periodic table varies from Moseley's is the fact that Mendeleev's table is arranged on the basis of the atomic masses of the elements.

Henry Moseley suggested that the elements should be arranged according to their atomic number, rather than their atomic masses. This cleared up many anomalies in Mendeleev's original table.
