In this video, we introduce Moseley’s law, which explains how periodicity is a property of an element’s atomic number rather than atomic mass. Also, we come

Moseley law graph

Moseley found that this relationship could be expressed by a simple formula, later called Moseley's Law.. where: is the frequency of the main or K x-ray emission line and are constants that depend on the type of line . For example, the values for and are the same for all K α lines (in Siegbahn notation), so the formula can be rewritten thus: Answer. Moseley's law states that the square root of the frequency of the emitted x-ray is proportional to the atomic number. Importance of Moseley's law: Using this law Moseley arranged K and Ar, Ni and CO in a proper way in Mendeleev's periodic table. This law was held to the discovery of many new elements like Tc (43), Pr (61), Rh (45). 0 suggestions are available.

Moseley found that this relationship could be expressed by a simple formula, later called Moseley's Law. where: is the frequency of the main or K x-ray emission line and are constants that depend on the type of line For example, the values for and are the same for all K α lines (in Siegbahn notation), so the formula can be rewritten thus: Hz

In a Moseley graph: A)the x-ray frequency is plotted as a function of atomic number B)the square of the x-ray frequency is plotted as a function of atomic number C Moseley needed some function of a nuclear property that increased in the same pattern, that is, by one for each element in turn. He found it in the K line of the X-ray spectra of each element.

Moseley's law for frequency of X-ray is given by for K-series b =1. for Kα line n1 = 1 and n2 = 2 ; for Kβ line n1 = 1 and n2 = 3. For Kα line the slope is and for Kβ line the slope is Hence the ratio of slope of Kβ line to that of Kα line is

JEE Main Characteristic x-rays are emitted from heavy elements when their electrons make transitions between the lower atomic energy levels. The characteristic x-ray emission which is shown as two sharp peaks in the illustration at left occur when vacancies are produced in the n=1 or K-shell of the atom and electrons drop down from above to fill the gap.
