Question

Henry Moseley improved Mendeleev's periodic table by reorganizing the elements by what property? A nonmetals, metals, and metalloids B number of energy shells C number of protons in the nucleus

Answer 1

Answer:

According to Moseley, similar properties recur periodically when elements are arranged according to increasing atomic number. Atomic numbers, not weights, determine the factor of chemical properties. Mendeleev ordered his elements in order of their relative atomic mass, and this gave him some problems.
