ResourceOn This Day - Nov 23 : Henry Moseley was born
He developed a law concerning the characteristic X-rays that are emitted by atoms, and thus allowed atomic numbers to be defined. Until this point, these numbers in the periodic table were simply an element’s place, rather than being associated with a physical property.
