**Henry Moseley (1887-1915)** []
 * "We find that an X ray bulb with a platinum target gives out a sharp line spectrum of five wavelengths which the crystal separates **
 * out as if it were a diffraction grating. In this way one can get pure monochromatic X rays. **
 * Tomorrow we search for the spectra of other elements. There is here a whole new branch of spectroscopy, **
 *  which is sure to tell one much about the nature of an atom." ~ Henry Moseley **

**About Henry Moseley:** ** Henry Moseley was born into a high achieving English family on November 23, 1887. With his mother, a decedent from a biologist and his father a biologist himself as well as a professor at Oxford, it's no wonder Moseley's initial interest was zoology. He was able to study this field at Eton after receiving a scholarship. After he completed that education, he worked his way through Trinity College achieving in math and science eventually earning himself a job at the University of Manchester working under the scientist R **** utherford. ** **Moseley's Research:**  **At Eton, the physics teacher was the first to show Moseley about x rays. When he was studying with Rutherford he used the x ray spectra to find out information about atoms. He measured the wavelengths of emissions from the different elements. When he compared ordering of the wavelengths with the atomic number he noticed to two sets of information corresponded with each other.**

**The Results of Moseley's Work:**  **Because of the coinciding patterns that Moseley found in the two sets of data, he was able to edit Mendeleev's** **periodic table so it was more accurate. Instead of organizing the table according to atomic mass, he rearranged** **it so it was ordered by atomic number. Because of this, many mysteries of the order of elements were solved; elements** **like iodine** **could finally be placed in the correct spot. Moseley was also able to predict the positions of elements not yet** **known.** **The periodic table that Moseley created based on atomic number is the basis of the modern periodic table seen** **today.**
