WebApr 24, 2024 · Mendeleev and Moseley are credited with being most responsible for the modern periodic law: When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties. The result is the periodic table as we know it today. WebPeriodic Table of Elements: The periodic table of elements used today is a direct result of Henry Moseley's contributions to atomic theory. The periodic table used during Moseley's life was the Mendeleev periodic table. This table arranged elements based on their atomic mass, with alterations made for their chemical properties.
Difference Between Mendeleev and Moseley Periodic Table
Henry Gwyn Jeffreys Moseley was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra. Moseley's law advanced atomic physics, nuclear physics and quantum physic… WebIn 1913, Henry Moseley experimented with x-rays of certain periodic table metals. His experiments and calculations of protons in the nucleus led him to classify periodic table … brew city beer gear
