atomic weight

nucleus size
nucleus size

electric charge

Answer 1

The correct answer is **atomic number**.

**Explanation:**
Henry Moseley proposed that the elements in the periodic table should be arranged by their atomic number rather than their atomic weight. He discovered that the atomic number correlates with the number of protons in an atom's nucleus, which reflects the fundamental nature of the elements. This concept resolved discrepancies in the arrangement of elements and allowed for a more accurate and organized periodic table that is still in use today.
