What did Henry Moseley determine that contributed to the understanding of an atom?

Answer 1

Henry Moseley is a Physicist. He used x-rays and discovered the atomic number of each element, that led to more accurate organization of the Periodic Table. He arranged the elements in the periodic table by the number of protons of the elements not on the basis of atomic weights of the elements.

Answer 2

In 1912, Henry Moseley, an English physicist showed that periodicity was a fucntion of the atomic number rather than of Atomic Mass. Our present periodic tables are now constructed using atomic number as the basis of arranging the elements and the periodic law being stated as, the physical and chemical properties of the element are periodic functions of their atomic numbers. This periodic recurrence of properties is emphasized by arranging the elements in a table such that elements with similar properties are aligned in a vertical column. This arrangement is called the Periodic Table.

Answer 3

He discovered that atoms of each element contain a unique positive charge in their nuclei

Answer 4

Answer 6

Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements.

Answer 7

Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements.

But Moseley hadn't a personal atomic theory.
