Henry Moseley - Chemistry

Henry Moseley (1887-1915): A British chemist, Henry Mosely studied under Rutherford and brilliantly developed the application of X-ray spectra to study atomic structure; Moseley's discoveries resulted in a more accurate positioning of elements in the Periodic Table by closer determination of atomic numbers.
