He expressed his observations mathematically as Where g is the frequency, z = atomic number and a, b constants. This is called Moseley's law. This law goes hand in hand with Bohr's atomic model. 9.
WebThe original periodic table developed by Mendeleev in 1869 consisted of elements arranged in order of increasing atomic mass. However, it was soon discovered that arranging elements in this manner did not correlate with the position predicted by their chemical properties. In 1913, Moseley found that there was a more fundamental …
