Denton Matthews Atomic History Timeline

Isaac Newton

Dec 25, 1642

~ Born December 25th 1642
~ He was born in England
~ He Built The First Telescope
~ He Contributed to all kinds of scientific theories.

John Dalton

Sep 6, 1766

~ Born September 6th 1766~ Born in England~ He was colour blind~ He studied Gases and thermal pressure.~ He realised that everything, a solid, a liquid, or a gas was made up of tiny particles.

Michael Faraday

Sep 22, 1791

~ Born September 22nd 1791~ Born in South London~ Learnt about atoms from Reading books~ Helped to design the electric motor~ He split molecules with electricity

Julius Plucker

Jun 16, 1801

~ Born June 16th 1801~ Born in Elberfeld, Germany~ He was a mathematician, physicist and chemist.~ He was the first to discover electron rays that were produced in a vacuum.

George Stoney

Feb 15, 1826

~ Born February 15th 1826~ Born in Oakley park, Ireland~ He was a physicist who introduced the term Electron for the unit of electricity~ He worked on molecule physics and kinetic theory~ He estimated the number of molecules in a volume of gas

Dmitri Mendeleeff

Feb 8, 1834

~ Born February 8th 1834~ Born in Tobolsk, Siberia~ He designed and grouped the periodic table~ He greatly contributed to atomic discovery through his work with the periodic table~ He also made a set of laws, called “The Laws Of Period”.

J.J. Thompson

Dec 18, 1856

~ Born December 18th 1856~ Born in Cheetham hill, England~ He discovered that the atom itself was made up of many tiny particles~ Others doubted his scientific claims, but as years passed, they too, began to believe that the atom was devisable.

Ernest Rutherford

Aug 30, 1871

~ Born August 30th 1871~ Born in Nelson, New Zealand~ Rutherford discovered that each atom had a nucleus~ He also discovered that the proton in each atom is positively charged.

Francis William Aston

Sep 1, 1877

~ Born September 1st 1877~ Born in Harborne, Birmingham, England~ Aston Studied Radioactivity and X-rays, which helped him later to develop the “Aston mass Spectrograph” ~ Astons Spectrograph Helped him to analyse beams of light and break them down into their individual colours.

Frederick Soddy

Sep 2, 1877

~ Born September 2nd 1877~ Born in Sussex, England~ He worked with Rutherford and the theory behind nucleus in atoms.~ He won the Nobel peace prize for chemistry in 1921~ He learnt that element change when they are exposed to radioactivity.

Niels Bohr

Oct 7, 1885

~ Born October 7th, 1885~ Born in Copenhagen, Denmark~ He made countless discoveries regarding atomic theory and quantum physics~ He studied with Rutherford, and proved that the atom had a positively charged nucleus, with a group of negatively charged electrons circling it.

Herny Mosely

Nov 23, 1887

~ Born November 23rd 1887~ Born in Weymouth, Dorset, on the south coast of England~ He worked on a theory about the charge of a nucleus.~ He figured out that the atomic number of an element was equal to the number of protons in the nucleus~ He worked on the Rutherford project and helped uncover many secrets about the atom

James Chadwick

Oct 20, 1891

~ Born October 20th 1891~ Born in England~ He Studied with Ernest Rutherford at Cambridge university.~ Chadwick discovered that it was possible to increase an atoms mass without an electrical charge

Louis De Broglie

Aug 15, 1892

~ Born August 15th, 1892~ Born in France~ He Grew up studying with his brother and learnt things about atoms from his brothers X-Ray studies~ Louis thought that electrons possessed a dual nature, with properties representative of both particle waves

Enrico Fermi

Sep 29, 1901

~ Born September 29th 1901~ Born in Rome, Italy~ Fermi discovered a process call fission, where an atomic chain reaction could be controlled.~ Fermi achieved success in creating a chain reaction necessary for a nuclear bomb to be built.~ The US Government swore Fermi to secrecy. Only he knew how to release energy from an atoms nucleus under controlled circumstances.
