On which atomic property proposed by Henry Moseley is the current periodic table of elements based

Answer 1

The current periodic table of elements is based on the atomic number, which was proposed by Henry Moseley. In 1913, Moseley conducted experimental work that established a clearer relationship between the atomic number and an element's properties, leading to the reordering of the periodic table. This replaced the earlier method of arranging elements by atomic mass, which sometimes resulted in inconsistencies, especially with isotopes and elements that did not fit the mass-based order. Moseley's work demonstrated that the atomic number, which corresponds to the number of protons in the nucleus of an atom, is the fundamental property that determines an element's position in the periodic table.
