Periodic Table Periodic Table Presentation Transcript

  • Periodic TableSarah McGibbon
  • Where It Came From✤ In 1869, Russian chemist, Dmitri Mendeleev, came up with a way to organize the elements that had been discovered at that time.
  • Organization✤ Mendeleev organized it by increasing atomic mass, the farther down and to the right the element is, the higher the atomic mass is. He then grouped them into groups or families, based on their physical and chemical properties.
  • Elements Relationships✤ The closer the elements are together, the closer they are in atomic mass, number and material
  • Potassium✤ Atomic Number: 19✤ Symbol: K✤ Atomic Mass: 39.0983✤ Potassium is found in bananas, milk and some meats
  • Gold✤ Atomic number: 79✤ Symbol: Au✤ Atomic Mass: 196.966569✤ Gold is found in things such as jewelry, old antiques and gold bars
  • Helium✤ Atomic Number: 2✤ Symbol: He✤ Atomic Mass: 4.002602✤ Helium is found in things such as balloons, cooling agents for nuclear reactors and supersonic wind tunnels
