What else can I help you with?
Who discovered the concept of the atomic number?
Henry Gwyn-Jeffreys Moseley in the 1910s.
Who developed the concept of atomic number?
The concept of atomic number was developed by physicist Henry Moseley in 1913. Moseley's work on X-ray spectra led to the realization that each element had a unique atomic number, which directly correlates to the number of protons in its nucleus.
Who discovered atomic number?
The concept of atomic number was proposed by Henry Moseley, a British physicist, in 1913. Moseley's research on X-ray spectra of elements led to the reorganization of the periodic table based on atomic number. His work established the modern understanding of the organization of elements by their atomic numbers.
What did Henry Moseley discover in science?
Henry Moseley discovered the concept of atomic number and its significance in organizing the elements in the periodic table. His work helped to establish a more accurate and systematic way of arranging elements based on their number of protons in the nucleus. This laid the foundation for the modern periodic table of elements.
Who showed that periodicity depended upon atomic number?
Henry Moseley showed that periodicity depended upon atomic number. He rearranged the periodic table based on atomic number rather than atomic mass, providing a more accurate representation of the periodic trends.
Who said the periodic table depended upon atomic number?
Henry Moseley
Who showed the periodicity depended upon atomic number?
Henry Moseley in 1913.
What scientist in 1913 aranged the elements by atomic number rather than atomic mass?
Henry Moseley
Who rearrange the periodic table by atomic number into the table you recognize today?
Henry Moseley
What did Moseley use to reorder the elements of Mendeleev periodic table?
Henry Moseley discovered a relation between X-ray spectra and the atomic number of chemical elements.
What did Henry Moseley change about the periodic table?
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.
Which scientist discovered that the atomic number rather than the atomic weight is more responsible for the properties of an element?
Henry Moseley, a British physicist, made this discovery in 1913 through his experiments with X-ray spectra. Moseley's work led to the reorganization of the periodic table based on atomic number instead of atomic weight.
