Storyboard Text

  • At around 400 B.C. Democritus claimed that matter is composed of tiny and indivisible particles called "atomos".
  • Hello, I am Democritus. I propose that all matter is composed of small particles called "atomos".
  • In the year 1808, John Dalton created the first atomic theory. His theory was that atoms were tiny indivisible solid balls .
  • Atoms are tiny solid balls that are indivisible.
  • John Dalton also said that all atoms of an element are alike and atoms of different elements join to form compounds.
  • In the year 1897, JJ Thomson found out that there are negatively charged particles inside the atom. He called these corpuscles but scientists then changed the name into what we call today as "electrons".
  • JJ Thompson used the cathode ray tube, which is a vacuum tube where beams of electrons passed through from left to right, and discovered electrons.
  • My atomic model is the "Plum Pudding" model. The negatively charged particles are the raisins while the dough is the positively charged part of the atom.
  • In the year 1910, Ernest Rutherford discovered the nucleus and he also discovered the protons inside the nucleus through the Gold Foil experiment.
  • I discovered that most of the particles went through the gold in the experiment. The atom had a dense center which I call the nucleus.
  • In Neils Bohr's 1913 model of the atom, electrons travel around the nucleus in well-fined paths called orbits (just like the planets orbiting the sun). 
  • Electrons in different orbits possess different amounts of energy. The orbit closest to the nucleus has the least energy and the orbit farthest has the most.
  • In 1932 James Chadwick discovered the neutrons found inside the nucleus.
  • The neutrons are found inside the nucleus and are uncharged thus giving them their name.
