what was his role in the field of x-rays?
The X-ray spectrometers as Moseley knew them worked as follows. A glass-bulb electron tube was used, similar to that held by Moseley in the photo here. Inside the evacuated tube, electrons were fired at a metallic substance (i.e. a sample of pure element in Moseley's work), causing the ionization of electrons from the inner electron shells of the element.

what is the purest form of iron called UNANSWERABLE what is this subsance? It is a chemical element with symbol Fe and atomic number 26. what is this number? Also known as the proton number (symbol "Z") of a chemical element - it is the number of protons found in the nucleus of every atom of that element. how is it related to an experiment conducted in 1913? The experimental position improved dramatically after research by Henry Moseley in 1913. who was this person? He 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. where was he from? Weymouth in Dorset what was his role towards explaining the atomic structure? His discovery showed that atomic numbers were not arbitrarily assigned, but rather, they have a definite physical basis.

Henry Moseley [SEP] Use of X-ray spectrometer
X-ray spectrometers are the foundation-stones of X-ray crystallography. The X-ray spectrometers as Moseley knew them worked as follows. A glass-bulb electron tube was used, similar to that held by Moseley in the photo here. Inside the evacuated tube, electrons were fired at a metallic substance (i.e. a sample of pure element in Moseley's work), causing the ionization of electrons from the inner electron shells of the element. The rebound of electrons into these holes in the inner shells next causes the emission of X-ray photons that were led out of the tube in a semi-beam, through an opening in the external X-ray shielding.
