Before Henry Moseley, the Periodic Table was arranged in order of increasing Atomic Mass. However, this arrangement did not allow all the elements to be placed into groups of similar chemical properties. Moseley rearranged the periodic periodic in order of increasing atomic number which did have all the elements in their correct groups.
Atomic number on the basis of Modern periodic law as on the view of Henry Mosely
Dimitri Mendeleev produced the first periodic table leaving spaces for elements that were not yet known in 1869; Henry Mosely determined the atomic number of elements and corrected some inaccuracies in Mendeleev's periodic table.
The Periodic Table of Elements was modified by the English scientist Henry Moseley in the year 1913. Moseley assessed the atomic number of the elements individually and organized the atoms according to increasing atomic number.
Dmitri Mendeleev is considered the creator of the periodic table of elements.
Yes depending on which scientists version of the periodic table you look at. Henry Moseleys ideas on the periodic table was the first to increase by atomic number.

Mendeleev developed the first periodic table and Mosely later modernized it.

Moseley discoverd that atomic numbers had an experimentally measurable basis. So he arranged his periodic table based on atomic numbers.
Henry Moseley first organized the modern periodic tabe by atomic number in 1913.
Henry Moseley made major contributions to physics regarding the atomic number. He also developed Moseley's Law which allowed for a more logical based sorting of elements on the Periodic Table.

Modern periodic table is invented by Henry Moseley.
