Mendeleev used atomic masses to classify the element, where as Moseley classified the element in terms of atomic number, he suggested that chemical and physical properties are the functions of the atomic number Elements in the Periodic Table is classified as Metals, Nonmetal and Metalloids. Normally Group 1 to 12 are metals...

In Mendeleev periodic table elements were arranged in the increasing order of their atomic masses and there were free spaces for the new elements which were not discovered at that time. This periodic table had more periods than groups.In Mosley periodic table elements were arranged in the increasing order of their atomic numbers and there were no free spaces for the new elements which were not discovered at that time. This periodic table has more groups than periods.
Mendeleev's periodic table was arranged in order of increasing atomic masses, whereas today's modern periodic table is arranged in order of increasing atomic number.
He developed and organized the Periodic Table of Elements
Dmirtri Mendeleev made the first periodic table. It was organized by elements according to the atomic mass. < notice it is atomic mass not number>
Dmitri Mendeleev developed the first periodic table. But the modern table was developed by Henry Moseley.
Dmitri Mendeleev developed the modern periodic table in 1869.
Dmitri Mendeleev developed the first periodic table of the elements.
He developed and organized the Periodic Table of Elements
Mendeleev was a Russian chemist who organized the periodic table.
Mendeleev's periodic table was organized in order of increasing atomic masses. He arranged elements having similar properties together.

Dmitri Mendeleev developed the first periodic table. But the modern table was developed by Henry Moseley.
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
