Atomic Theory by Nicol Hernandez https://padlet.com/hernandezn21/jtfyyaduhivp5evv History Of Atomic Theory en-us 2020-09-29 12:48:47 UTC 2020-10-03 00:17:45 UTC hello@padlet.com J.J THOMSON hernandezn21 https://padlet.com/hernandezn21/jtfyyaduhivp5evv/wish/799003348       According to Anne Marie                    Helmenstine, Ph.D 
                     (2/2/20)
  • His discovery changed how people viewed atom
  • His model consisted of positve and negative charges 
  • Stated that an atom was a sphere 
  • Both positive and negative charges were embedded with it
            According to Weebly 
  • "Plum Pudding Model"
  • spehere atom filled with positive charge was know as the "pudding"
  • Negative charged electrons were the "plum" 
  • Positive fluid kept the negative fluid charged

  • All matter is made of very tiny atoms 
  • Atoms can't be created or destroyed 
  • The elment fo the given atom are identical in mass and chemical properties 
  • Different elements in atoms do not have teh same mass and chemical properties
According to PLAY chemistry (10/9/16) 
  • Atoms can't be created or destroyed however his analogy FAILED

  • 911 he perfomed an expirement 
  • During his expirement he bombarded a thin foil of a heavy metal 
  • Observed scattering of rays after hitting the foil 
  • Used a circular zinc sulphide screen
  • Flash of light produced on screen 
  • Atom occupy small volume 
  • Concluded that there is empty space in the atom

                    (1/27/20) 
  • His model cosisted of small positive charged nucelus orbiting by negative charged electrons
  • Energy of the orbit is related to the size 
  • Radiation is observed or emitted when an orbit moves from a orbit
  • His model makes poor predections 
      According to MBD Alchemie            (5/11/18) 
  • Special orbots are callled dicrete orbits or energy levels. 
  • Electrons revolve around the nucleus

  • Matter is composed of tiny particles
  • A Tomos = Uncuttable 
  • Attributed properties of  each substance to form of the atom 
  • Thought that iron were stuck together 
            According to Weebly 
  • Atoms are indestructuble 
  • Only used knowledge and philosical means 
  • Used analogies of his expirience to create a picture of atoms
