Atom Theory Development

  • Joseph Priestly and Antoine Lavoisier

    Joseph Priestly and Antoine Lavoisier
    Joseph Priestly and Antoine Lavoisier discovered oxygen, which laid the foundation and groundwork for modern chemistry as we know it.
  • Humphry Davy

    Humphry Davy
    Humphry Davy utilized electricity to push the bounds of science and expand the field of chemistry. His use of electricity would help find new elements and study them.
  • Dmitri Mendeleev

    Dmitri Mendeleev
    Dmitri Mendeleev created the modern periodic table as we know it. He organized the elements and studied their properties to create an organized table that still serves us today.
  • Marie Curie

    Marie Curie
    Marie Curie's work with radioactivity helped give us insight into the atom and helped us understand it more. She discovered radioactivity through radium and polonium and created the term radioactivity.
  • Harry Moseley

    Harry Moseley
    Harry Moseley researched atomic numbers and redefined the way that we look at the periodic table. He studied the x-ray spectrum through the diffraction of crystals to link wave lengths and atomic numbers to each other.
  • Glenn Seaborg

    Glenn Seaborg
    Glenn Seaborg's discovery opened the door to discovering new elements that had never been studied before. He discovered Plutonium and would go on to discover more radioactive elements.
