Unformatted text preview: t 1915) was an English physicist. Moseley's outstanding
contribution to the science of physics was the justification from
physical laws of the previous empirical and chemical concept
of the atomic number. This stemmed from his development of
Moseley's law in X-ray spectra. Moseley's Law justified many
concepts in chemistry by sorting the chemical elements of the
Periodic Table of the Elements in a quite logical order based on
Moseley's law advanced atomic physics by providing the first
experimental evidence in favor of Niels Bohr's theory, aside
from the hydrogen atom spectrum which the Bohr theory was
designed to reproduce. That theory refined Ernest Rutherford's
and Antonius Van den Broek's model, which proposed that the
atom contains in its nucleus a number of positive
nuclear charges that is equal to its (atomic) number in the
periodic table. This remains the accepted model today.
When World War I broke out in Western Europe, Moseley left
his research work at the University of Oxford behind to
