Isaac newton
Isaac newton was born 1 Jan 1642. Isaac Newton thought that there was small solid masses that were in the air in motion -
John Dalton
Born 6 Septbember 1766
John Dalton based to theory on three important Propositions: all matter is composed extremely small, indivisible and indestructible particles and they were called atoms. Atoms of one element they were all the same in very way but were different from the atoms of every other element. Point where matter is not broken down into anything smaller. Atoms are tiny particles. John Dalton discovered that some gases can be combined to certain proportions even two different compounds -
Micheal Faraday
Michael faraday was born September 22nd 1791, Hampshire. Michael faraday wanted to learn more and discover the effects of electricity splitting molecules. Michael Faraday Studied effects of electricity on solutions and was named “electrolysis” which is splitting molecules with electricity which developed the law of electrolysis, Michael Faraday was a proponent of atomism. He changed the way people look at atoms -
Julius Plücker
Born June 16, 1801. Julius Plücker was the first ever person to use a device called the vacuum tube with the capillary. Julius Plunker change the views because he could create an magnetic field by applying an electromagnet to the tube (Geissler Tube) -
G.J Stoney
G.J Stoney Was born 15/5/1826. G.J Stoney’s Research laid the foundations for J.J Thomas to the eventual discovery of the particle. G.J Stoney was noted for his scientific work is the conception and calculation of the magnitude of an atom/ Particle of electricity and he coined the term electron. He was he first person to called it an electron -
Ernst Runtherford
Ernst Rutherford worked under J.J Thomson and completed the experiment that was called “plum Pudding”. Ernst Rutherford is most know for his work on splitting the atom. He was the person lead people to the experiment Split the nucleus. The Study on Rutherford on uranium and thorium got renamed to alpha and beta. -
Francis Aston
Francis Aston was born 1st of September 1877. Francis work as J.J Thomson’s assistants at the Cavendish Laboratory. Francis Aston, using an mass spectrograph he could discovered isotopes and where isotopes are. -
Frederick Soddy
Frederick Soddy Was born 2nd of September 1877. Fredrick wanted to learn more about the atom after working with Sir Ernest Rutherford. Soddy work with Ernest Rushford and these to were working on radioactivity and they were both able to Identify that radioactive elements have an anomalous behavior because they decayed into another element and because of this decay it generates alpha beta and gamma radiation. Frederick Soddy was an English chemist that in 1912 he thought that the same element -
Albert Einstein
Albert Einstein was born 14th March 1879. Albert Einstein was against atomic theory so the other sciences wanted to prove to him that is shouldn’t be against it. Albert Einstein was noted for being against the atomic theory -
Niels Bohr
Niels Bohr was born 7th of October 1885. Albert Einstein criticized atomic theory so Niels Bohr wanted to make models to explain it. Niels Bohr did developed a explanation for the atomic structure that underlines similarities to the periodic table. He help by contributing to the developed of the atomic structure. -
H.G.J Moseley
H.G.J Moseley was born 23 November 1887. He could find the charges inside the nuclei of the atom, by using a device called a x-ray tubes and this device could determined tthe inside of the nuclei. -
James Chadwick
James Chadwick was born on the 20th October 1891. James Chadwick always had predicted that the atom would have an neutron inside of it. James Chadwick Discovered the neutron by using alpha particles he discovered a neutral atomic particle with a mass close to a proton and this help him discover the neutron in to atom. James Chadwick change atomic theory by discovering the neutron
