One of the central concepts in chemistry consists in the electronic configuration of atoms. This is equally true of chemical education as it is in professional chemistry and research. If one knows how the electrons in an atom are arranged, especially in the outermost shells, one immediately understands many properties of an atom...

By Eric Scerri This year marks the 100th anniversary of a remarkable discovery by an equally remarkable scientist. He is Henry Moseley, whose working career lasted a mere four years before he was killed in World War I shortly before his 26th birthday. Born in 1887 in England, Moseley came from a distinguished scientific family.
