Abstract

When discovered by Wilhelm Conrad Röntgen (1845-1923), X-rays caused fascination and great debate among people in the late 19th and early 20th centuries. Studying the properties of this new type of radiation led to an understanding of the structure of matter. In this work, we will try to highlight the importance of understanding this type of radiation and guide the reader toward a fundamental reflection: X-ray studies and their application in the identification of crystalline structures, which converged to the interpretation of chemical bonds. Although the justifications for the bonds are not addressed, it will be possible for the reader to identify the collective construction that will lead to the clarification of how atoms bond.
