how did moseley establish a more accurate periodic table? by arranging the elements according to atomic mass instead of atomic number by arranging the elements according to atomic number instead of atomic mass by arranging the elements into horizontal periods by arranging the elements into vertical groups
Answer
Brief Explanations:
Moseley used X - ray spectroscopy to show that atomic number was a more fundamental property than atomic mass for organizing elements. He arranged elements by atomic number, which led to a more accurate periodic table. Arranging into horizontal periods or vertical groups was not Moseley's key contribution to accuracy.
Answer:
by arranging the elements according to atomic number instead of atomic mass
