Isaac Newton
Isaac newton was influenced by a man called Democritus when he discovered that all matter is made up of small unbreakable elements he called atoms. Isaac Newton then completed experiments that allowed him to develop laws and theories on gravitatonal force that gave us a better understanding of the universe and gave future scientists the tools to discover how to enter space. Isaac showed us that things fall down and not up because gravity is keeping everything on the ground. -
John Dalton
John Dalton was influenced by a french chemist called Antonie Lavoisier who discovered the compunds containing more than oe element always had the same amount of each element. This is when Dalton suggested that matter could not be broken down into anything smaller, calling these tiny particles atoms. John Dalton showed us that different types of atoms could combine together and potentially form various known elements. -
Michael Faraday
Michael faraday was influenced by John Dalton who proposed an atomic theory on atoms based upon measurable properties of mass. This then lead Faraday to show us the effects oof electricity on solutions and that molecules could be seperated using electricity.He showed us that electricity is in fact a force not an unknown fluid. -
Julius Plücker
Julius Plückerwas influenced by Michael Faraday who established the two laws of electrochemistry. Julius Plücker then built one of the first cathode ray tubes (discharge tube). He showed us that you can make a magnetic field by applying an electromagnet to a tube of rare field gases. -
George Jonhstone Stoney
G.J Stoney was inspired by James Clerk Maxwell who proposed his theory that electromagnetism made connections between light and electromagnetic waves. This inspired G.J Stoney to create his own theory. G.J Stoney suggested that electricity was made of negative particles he refered to as 'electrons'. Stoney improved on Balmer's law on the hydrogen spectral series of lines. He discovered relationships between three of the four and developed laws for them. -
Dmitri Mendeleev
Smitri Mendeleev was influenced by J plucker who created the first cathode-ray tubes. Dmitri was noted for, for creating the periodic law which is elements arranged into 7 groups in which have similar properties (according to their weights). Dmitri gave us an easier understanding of the properties of atoms by putting them on a table making them easier to remember and read. -
Joseph John Tomson
Joseph John Tomson was inspired by Henri Becquerel who discoverd radiation. J.J Thomson then used a CRT to experimentally determine the mass ratio of an electron. He showed us that electrons are a component of an atom and that atoms are invisible. He also assumed that electrons were negativly chareged and that they possibly rotate in rings. -
Ernest Rutherford
Ernest Rutherford was inspired by Joseph John Thomson who discovered the mass ratio of an electron. Rutherford then named radiations released from uranium and thorium, alpha and beta. He also established that the nucleus of atomic bullets are positivly charged and that electrons are located outside the nucleus. He improved on JJ. Thomson’s theory, showing us that alpha particles can only deflect from a center of concentrated charge containing most of the atoms mass. -
Francis William Aston
Aston was inspired by Moseley when he created Moseley's law by experimenting with x-rays and discovered a regular mathematical relationship beween the x-rays wavelengths. Aston discovered the existence of isotopes from using a mass spectrograph. Aston made the mass of the oxygen isotopes and all the other isotopes by creating a Whole Number Rule. -
Fredrick Soddy
Fredrick Soddy was inspired by Max Planck after he used the idea of quantization to describe how a hot, glowing object produced light. Soddy then discovered the breakdown of radioactive elements. He showed us that radioactive elements contain more that one atomic mass calling this concept 'isotope'. A women called Margaret Todd suggested the name 'Isotope' too Fredrick Soddy. -
Niels Bohr
Niels Bohrwas influenced by Ernest Rutherford after he explores uranium's radioactivity and discovered two type of radioactivity that differed from their x-rays, calling them Alpha and beta rays. This then led to Bohr's discovery of the atomic structure and how atoms are built us of orbital shells of electrons. This changed the way we looked at atoms by showing us the structure of the atom and how electrons circle thenucleus. This then helped future scientists with their reaserch of the atom. -
Henry Moseley
Moseley was influenced by Ernest Rutherford because of his theory of the atom proposing that the nucleus of an atom was positively charged and that electrons are located outside the nucleus. Henry then used x-ray tubes to determine the charges on the nuclei of most atoms and that the atomic number of an element is equal to the number of protons in nucleus. He showed us that certain characteristics emitted from chemical elements are equal to the square number close to the elements atomic number. -
James Chadwick
James Chadwick was inspired by Schrodinger when he combined equations from the de Broglie equation to generate a mathematical model for the dispersal of electrons in an atom. James Chadwick discovered a neutral atomic particle that had a mass close to a proton using alpha particles discovering the neutron. He discovered the neutron and was able to determine that its mass was around about 0.1% more than a proton’s. -
Louis de Broglie
Louis de Broglie was inspired by Albert Einstein when he created the theory of relativity and the mass energy. This formula was then used in nuclear power and other things. He discovered that electrons are similar to particles and waves as they both have a dual nature. His discovery changed the way we view the atom as he suggested that particles of light and matter were the same behavior and that particles can behave like waves and radiation (waves) can behave like particles. -
Enrico Fermi
Enrico Fermi was inspired by James Chadwick when he used alpha particles to discover a neutral atomic particle that has a mass similar to a proton. This particle was called a neutron. Enrico conducted the first controlled chain reaction of the nucleus of an atom that released energy from atom nucleus. Enrico Fermi discovery changed the way we view the atom because he developed a theory of beta decay. Also that the neutron decaying to a proton emits an electron and a neutrino.
