Born on November 23, 1887
Born in Weymouth, Dorset, United Kingdom
Family had a scientific background
Went to Eton College


In 1910, graduated from Trinity College of the
University of Oxford. After he earned a
position in the laboratory of Ernest Rutherford
at the University of Manchester.
Died in the Battle of Gallipoli in 1915

Through observations and measurements of
the x-ray spectra of various of chemical
elements obtained by diffraction in crystals, he
discovered a systematic relation between
wavelength and atomic number; known as
Moseley’s Law.


He predicted a number of missing elements
and their periodic numbers in the periodic
table
His method in x-ray crystallography sorted out
many chemical problems scientists couldn’t
previously solve



He was apart of Rutherford’s research group
Moseley arrived in Manchester weeks before
Rutherford published his nucleus paper when
he started working on his atomic number work
Rutherford did not support the idea of Moseley
studying x-rays but he liked Moseley
enthusiasm and let him do it


Rutherford didn’t propose the existence of the
neutral particle until 1920; the neutron
James Chadwick, another of Rutherford’s
students, discovered the neutron in 1932 and
won the Nobel Peace Prize in 1935 for his
findings


In 1913, he proposed the idea of the
relationship was a function of the positive
charge on the nucleus.
He rearranged the periodic table by using the
atomic number instead of atomic mass to
represent the progression of elements.
