Which scientist proposed that atomic number is more fundamental proper...
Henry Moseley proposed that atomic number is a more fundamental property of an element than its atomic mass.
Explanation:
- In the early 20th century, scientists were trying to understand the structure of atoms and how the elements were related to each other.
- One of the key questions was how to organize the elements in a meaningful way. Dmitri Mendeleev had created the periodic table based on atomic mass, but some elements didn't fit into the pattern.
- Lothar Meyer had suggested that there might be a relationship between atomic volume and atomic weight, but this idea didn't gain much traction.
- Henry Moseley, working at the University of Manchester in England, was able to solve the problem by studying the X-ray spectra of various elements.
- He found that each element had a unique X-ray pattern, and that this pattern was related to the element's atomic number (the number of protons in the nucleus).
- Moseley proposed that atomic number should be used to organize the elements, rather than atomic mass.
- This idea was quickly adopted by the scientific community, and the modern periodic table is based on atomic number.
In summary, Henry Moseley proposed that atomic number is a more fundamental property of an element than its atomic mass because it is a more fundamental characteristic of the atom itself.
