What is Atomic Number & Mass Number - The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. Visit BYJU'S to learn more about atomic numbers.
(Authors who do not wish to use symbols sometimes write out the element name and mass number—hydrogen-1 and uranium-235 in the examples above.) Britannica Quiz Facts You Should Know: The Periodic Table Quiz The term nuclide is used to describe particular isotopes, notably in cases where ...

This study determined the interaction of radiation parameters of four biomaterials as attenuators to measure the transmitted X-rays spectra, the mass attenuation coefficient and the effective atomic number by spectrometric system comprising the CdTe detector. The biomaterial BioOss(®) presented s...
The atom-number fluctuations are especially important for the applications related to quantum information science and matter-wave interferometers [43], including Ramsey [44,45] and Mach–Zehnder [46] on-chip interferometers. In the literature, there are also other interesting discussions of the atom...
