He discovered that each element has its own atomic number.
In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore resequenced the table by nuclear charge rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
Henry Moseley reorganized the periodic table based on atomic number instead of atomic mass, thereby providing a more accurate and clear arrangement of elements. This reorganization helped to explain the discrepancies and predict properties of certain elements that were not well-understood before.
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.
Henry Moseley was a British scientist who made significant contributions to the understanding of the periodic table of elements. He developed the concept of atomic number, which is now used to organize the elements in the periodic table based on the number of protons in the nucleus. Moseley's work helped to establish a more accurate and systematic arrangement of the elements.
Henry Moseley contributed to the periodic table by arranging elements based on atomic number rather than atomic mass, establishing the modern periodic law. His work led to a more accurate arrangement of elements and a better understanding of their properties. Moseley's discovery helped fill gaps in the periodic table and laid the foundation for the modern understanding of the structure of atoms.
The mother of Henry Moseley was Anabel Gwyn Jeffreys Moseley.
Dobereiner, Newland , Mendeleev are responsible for development. Modern periodic table was created by Henry Moseley.
Henry Moseley showed elements in the periodic table should be in order by their atomic number instead of atomic mass.

Henry Moseley sorted the chemical elements on the Periodic Table in order by their atomic numbers. Moseley was a British chemist who had studied under Rutherford.

Moseley's periodic table was developed by English physicist Henry Moseley in 1913. He rearranged the elements on the periodic table based on their atomic number rather than atomic mass, which led to the modern form of the periodic table. Moseley's work provided a clearer understanding of the organization of elements and their properties.
He found the number of protons an element has. present periodic table is according to it.
