In a famous paper he announced how he had experimentally verified a disputed hypothesis of A. van den Broek.
In a famous paper he announced how he had experimentally verified a disputed hypothesis of A. van den Broek. His namesake plot allowed for the determination of the Z values, or number of electrons, for many elements. With this information he correctly concluded that there were 14 rare earth elements and there were only 92 elements up to and including uranium. This was partly made possible by his discovery that an elements x-ray spectrum could be used to deduce its atomic number. FTP, name this British physicist perhaps more famous for dying at Gallipoli.
