EARL LIFE



His parent were both from well-educated families. His father,who wazas also named henery was professor of anatomy and physiology. his mather, Amabel was the daughter of a barrister who had changed careers to become a mallusc biologicst Some time after arriving at Eton he decided the school’s physics lessons were too easy, so he worked on the subject independently. Aged 18, he won Eton’s physics and chemistry prizes.

Already a high achiever, he was admitted in 1906 to the University of Oxford’s Trinity College, where he studied physics. There he disappointed himself. He was suffering badly from hayfever when he sat his final exams. He got a second class honors degree in physics, not the ‘first’ he had hoped for and expected.




EDUCATION

Henry moseley  was educated in private school. His frist school was summer field school- an elementary school. eton college, trinity college, oxford, university of oxford, and university of manchester. he study physiologist.

EARLY SCIENCE CAREER

He was admitted in 1906 to the university of oxfords trinity college , and university of manchester he study physiologist, there he disappointed him self

ATOMIC THEORY

In 1912 he attempted to use high positive  roltages to pull betaparticles high energy electrons back into their radio active source, but moseley hope to use the results to shed light on one of the predictions of Albert Einsteins special theory of relativity, that massin creases with velocityWorking in Rutherford’s group, it was inevitable that Moseley would work with radioactive chemical elements.After becoming familiar with the field, he went beyond experiments others had thought of and came up with his own particular twist.

HOW WAS THIS CONTRIBUTION ACHIEVED

His age was only 27. His death is all the more piognant for what he might have achieved. few achieved in a lifetime of research what he achieved in a career of just 40 mouths

IF THE CONTRIBUTION INCLUDED A MODEL

Moseley got a straight line when he plotted the square roots of element x-rays frequancies against elements atomic number. adding protons produces a new elements hydrogen has aone proton so it atomic number sone. add a proton and you heluim with atomic number two. add number proton and you get lithium with atomic number three, ect

WHAT OTHER CONTRIBUTION DID HE MAKE

Engineer, during his time as an engineer, he wrote several other. papers about the possiblies of the x-rays spect but none of this research was even materialized.

WHOSE WORK DID HE USE IN THEIR STUDY

He didn't use anyone's work, but in 1913 moseley celebrated his 26th birthday. Dmitri Mendeleelrs periodic table was older than Henry's. it had been around for 44 years. new chemical elements were still being discovered and a added to it by Henry Moseley.

WHOSE WORK CAME AFTER CONTRIBUTIONS

Albert Einstein rewrote the laws of atoms. He capletely changed the way we understand the behavior of things basic as light, gravity and time.

COLLEAGUES

Mendeleer's table was nine tenths of the way there, but needed one imprtant modification before it became the modern periodic table the use of atomic number as the organizing priniple for the periods. iodine has a high er atomic number than tellurium so even though he didn't know why, mendeleer was right to place it after tellununo  all

PUBLICATION

At the end of november he pulished famous step ladder, showing the increasing frequency of the x-rays from calcuim to cooper. He pulished his law on what he called the Slenderest of evidence, he later rindicated the law with investigation of father elements.

AWARDS

In the year 1919 ahter he died, he henry moseley was awarded the malteucci medal naihed after the italian of same nane and adjudicated by the Italian society of sciences. He won a award posthumously for his contribution to physicist and chemistry.

LATER YEAR

Moseley's work had a huge impact on chemists understanding of the atom the periodic table. There is no doubt that olospely would have been awarded the Nabel prize. the first war in 1914. in 1915 he was killed in the disastrous invasion of Turice he didn't do any after working atomic theory

Furthmore just like Mendeleev had  done 44 years earlier, moseley saw gaps in his new periodic table.He predicted the existence of four new elements, with 43, 61, 72, and 75 protons. These elements were discovered later by other scientists; we now call them. Technetium, promethium, hafnium, and rhenium.
