Moseley - His contribution To Physics and Chemistry
Seaman’s Barmy Army
What was his contribution to Science?
British Physicist, Henry Moseley is known most famously for his
establishment of the Periodic Table of Elements.
In a short career much of the research he did contributed to the science
Many scientists believe if Moseley had lived longer he would have
contributed a great deal more to atomic structure and that he would
have also earned the Nobel Prize in Physics.
Born in Weymouth, Dorset – 23rd November 1887
His family were rich, aristocratic and scientifically accomplished.
Henry Nottidge Moseley, his father, was a biologist and also a professor of
anatomy and physiology at the University of Oxford.
John Gwyn Jeffreys, his grandfather, was a biologist and conchologist
It was not surprising that Moseley showed a great interest in the sciences
As a child he attended Eton
He graduated from Trinity College
– University of Oxford.
Work and Research
At the University of Manchester,
Moseley carefully observed and
measured the X-ray spectra of various
chemical elements obtained by
diffraction in crystals.
Through his studies he discovered a
pattern – a systematic relation between
wavelength and atomic number. A
discovery known as rather brilliantly –
Contribution to Chemistry and the Atom
Moseley’s work in early X-ray crystallography
was able to complete many chemical
problems, some of which had baffled
chemists for many years.
Problems such as the irregularities in the
location of elements such as Argon and
Potassium; the positioning of the inner
transition elements in the Periodic Table – all
could now be clarified on the basis of the
End of his Era
In 1914, Moseley planned to
continue his studies in atomic
structure at the University of
Oxford – resulting in his
resignation from the university of
His plans were cut short, on
August 10th 1915 he was shot dead
during the Battle of Gallipoli in
Many Physicists believe he would
have gone on to win the Nobel
Prize in Physics.
