WebHenry Moseley decided to organize the periodic table by atomic number in 1913. The atomic mass issues were resolved as a result of this. What changed the periodic table from Henry Moseley to what we use today? He used self-built equipment in 1913 to demonstrate that the number of protons on every element determines its identity uniquely. 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 elements according to the atomic number. This experiment by him was called Henry Moseley’s Atomic Theory. He signified the atomic number with the letter Z.
