WebWhen electrons were discovered 27 years later, Mendeleev revised the periodic table. In 1913, English physicist Henry Moseley (18871915) restructured the periodic table by basing the elements’ order on the number of protons (atomic number) instead of atomic mass. HOW TO LEARN THE PERIODIC TABLE Web4) It was not discovered yet., After Moseley's discovery in 1913, the periodic law stated that physical and chemical properties tend to repeat periodically when elements are arranged according to what trend? 1) decreasing atomic mass 2) decreasing atomic number 3) increasing atomic mass 4) increasing atomic number and more.

WebIn 1913, Moseley found that there was a more fundamental property to elements than their atomic weight. This led Moseley to discover the importance of the atomic number. He discovered that every element’s unique identity and property could be determined by the number of protons in its nucleus. This discovery also enabled him to predict the ...
