Who discovered atomic number?
The concept of atomic number was proposed by Henry Moseley, a British physicist, in 1913. Moseley's research on X-ray spectra of elements led to the reorganization of the periodic table based on atomic number. His work established the modern understanding of the organization of elements by their atomic numbers.

Who discovered the atomic-number?
The atomic number was not discovered, as such. It's only when scientists realised that there were such things as atoms and the weights of them varied that they put them into some sort of order. So the lightest (hydrogen) is atomic number 1 and the next (helium) is 2, and so on.
