Henry Gwyn Jeffreys Moseley (/ ˈ m oʊ z l i /; 23 November 1887 – 10 August 1915) was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra.

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). 莫斯利定律（Moseley's law）是一個描述從原子發射出來的 X-射線性質的經驗定律。這一定律的結論是原子的電子層受激發（例如用高能貝他射線轟擊該元素做的靶板）產生的 X射線的頻率的平方根與元素的原子序數成線性比。 A Moseley Law is the square-root of the frequency of an x-ray spectral is proportional to the difference between the atomic number and a constant which depends only on the series. ⓘ Moseley’s Law [sqrt(v)] Moseley's law is an empirical law concerning the characteristic x-rays that are emitted by atoms. Until Moseley's work, "atomic number" was merely an element's place in the periodic table, and was not known to be associated with any measureable physical quantity.

rial. Use Moseley’s law to determine the atomic number of the target material. (Rydberg’s constant = 1.1 107 m 1.) Solution: The characteristic X-ray is emitted when an electron in L shell makes a transition to the vacant state in K shell. In Moseley’s equation, p n = a(Z b), the parameter b ˇ1 for this transition because electron from L shell

Problem from IIT JEE 2014 If $\lambda_\mathrm{Cu}$ is the wavelength of $K_\alpha$ X-ray line of copper (atomic number 29) and $\lambda_\mathrm{Mo}$ is the wavelength of the $K_\alpha$ X-ray line of molybdenum (atomic number 42), the the ratio … Moseley's law Moseley investigated systematically, the characteristic radiations emitted by different targets. Based on his experiments, he has concluded that the frequency of the spectral line in the characteristic X-ray spectrum is directly proportional to the square of the atomic number (Z) of the element considered. Moseley’s work provided an unambiguous justiﬁcation for ordering the elements in the periodic table according to atomic number Z, rather than Mendeleev’s original ordering by atomic weight A. This relation is now known as Moseley’s Law. C and σ are constants with C ≈ R (Rydberg constant) and σ ~ 1. σ is known as the screening constant.

Moseley's law is an empirical law concerning the characteristic x-rays that are emitted by atoms. It is historically important in quantitatively justifying the conception of the nuclear model of the atom, with all or nearly all positive charges of the atom located in the nucleus, and associated on an integer basis with atomic number.
