-
He was born on September 6, 1766 in Eaglesfield, England
-
In 1794 he was elected a member of the Manchester Literary and Philosophical Society. Also, not so long after he made his first thesis about "Extraordinary facts relating to the vision of colours", in which he theorised that deficit on the perception of color was caused by discolouration of the liquid medium of the eyeball.
-
He becomes a secretary of the Manchester Literary and Philosophical Society in 1800.
-
He presented an important series of essays on the constitution of mixed gases, steam and other vapours pressure on different temperatures, both in a vacuum and in air, on evaporation, and on the thermal expansion of gases. These essays were named "Experimental Essays". They were published in the "Memoirs of the Lit & Phil" in 1802.
-
In 1803 John Dalton, proposed his atomic theory of matter, which would later state that as temperature rises, gasses expand, and the cause of the "Aurora borealis", otherwise known as the Northern Lights, visible in Sweden. Then on October 21, 1803, John Dalton first announced of his famous atomic theory.
-
In 1810, Sir Humphry Davy asked Dalton to offer himself as a candidate for the fellowship of the Royal Society, but Dalton turned him down. It is possibly because of economical reasons.
-
In one of the memories that was read in 1814, Dalton explains the principles of volumetric analysis.
-
In 1824 he was made a corresponding member of the French Science Academy.
-
The first part of his second volume was issued in 1827. However, the second part of vol. ii. never came out.
-
In 1830 john was elected as one of its eight foreign associates in place of Davy.
-
Born in the west of Siberia, Russia.
-
Dalton had a minor stroke in 1837.
-
Dalton had a second stroke in 1838 which left him with a speech impediment, though he was still able to do experiments.
-
In May 1844 he had another stroke and then the 26th of July he wrote down his last meteorological observation.
-
On July 27, in Manchester, Dalton fell from his bed and was found dead by his attendant. He had forty thousand Manchurians who went to his funeral to pay their respects. He was buried in Manchester's Ardwick cemetery which is now a playing field, but pictures of the original grave are published.
-
In 1840 an essay about the phosphates and arsenates, was refused by the Royal Society, but he published it himself because he was insistent on publishing it. He did the same things later on with four other essays, two of which contained his discovery about the the atom theory and about some anhydrides when dissolved.
-
J.J Thomson was born in Cheetham Hill, near Manchester, UK.
-
He wrote the book 'Organic Chemistry' which students could not comprehend. Mendeleev knew the reason behind the confusion of the students was because the elements were not organized on a table.
-
He began to write the 'Principles of Chemistry' for the organization and explanation of the known ‘Typical’ elements: Oxygen, carbon, nitrogen, hydrogen.
Later on he added the halogens. -
He organized the elements out and filled out most of the elements that were still a mystery. Dmitri predicted the atomic masses of each one and placed them where he thought they belonged.
-
In the village of Brightwater, New Zealand's South Island.
-
J.J Thomson earned a membership in the prestigious Royal Society and was appointed Cavendish Professor of Physics.
-
He was born in Copenhagen, Denmark.
-
Born in Vienna, Austria. Developed Quantum Physics.
-
He presented his research along with his table of elements.
-
Born in Cheshire, England
-
J.J. Thomson's son Geroge Paget Thomson was born. George became a physicist and won a Nobel Prize.
-
Named director of Russia’s new Central Board of Weights and Measures.
-
Thomson began studying cathode rays, which are glowing beams of light that follow an electrical discharge in a high-vacuum tube.
-
From Canterbury College. He taught children for a short time. Then he won a scholarship, he went to the University of Cambridge in UK, working in J. Thomson's Laboratory
-
J.J Thomson discovered the electron experimenting with cathode rays.
-
After being homeschooled until 11, Schrödinger is moved to a formal school.
-
Rutherford studied the radiation emitted by uranium. He discovered two different types of radiation; alpha and beta
-
Here, he met his mentor Fritz Hasenlöhr
-
Received the Nobel Prize for his discovery of the electron.
-
His students showcased a copy of the Periodic Table in his honor at his funeral in St. Petersburg.
-
-
Chadwick studied in Manchester University.
-
a concentration of mass in the center of the atom
-
E. R. and a group of researchers, investigated what caused the alpha particles to be deflected from their straight-line paths. He proposed a new model for the atom, replacing J.J. Thomson model.
-
Bohr completed his doctorate in the Copenhagen University under the physicist Christian Christiansen.
-
James Chadwick graduated from the Honors School of Physics.
-
He moved to England and did experiments at Trinity College under J. J. Thomson (the discoverer of the electron). Then he did some others at the University of Manchester under Ernest Rutherford (the discoverer of the nucleus and the structure of atoms).
-
Bohr gets married to Margaret Nørlund, the sister of a mathematician.
-
James Chadwick worked on Radioactivity with his teacher Ruthford in Manchester city.
-
James Chadwick finished his studies and received a Masters of Science.
-
In this year Bohr proposed his model of the atom and how it is structured.
-
After finishing his studies and in the middle of doing some research in Vienna, he was drafted.
-
Induce nuclear reaction in a stable element
-
He received an Award for his Ph.D. from Cambridge University.
-
He was awarded a Nobel Prize in physics for his contributions to the structure of the atom.
-
For his research and findings of the elements of the periodic table.
-
Schrödinger comes up with a formula that allows to solve for the possible place of an electron at a certain moment
-
James Chadwick proved the existence of neutrons.
-
"for the discovery of new productive forms of atomic theory"

Bohr contributed with the US Atomic Energy Project during World War II.
-
It was about lectures he gave in Berlin about the relationship between quantum physics, chemistry, and genetics.
