This educational overview explores the development of atomic theory, starting from Democritus's idea of atoms to Dalton's recognition of various types of atoms, exemplified by gold and iron. It highlights Thomson's discovery of the electron, Rutherford's identification of the proton, and Bohr's model of atomic structure, which resembles our solar system. Additionally, it explains that different electron orbitals possess unique energy levels and that atoms can form compounds, such as water, which consists of hydrogen and oxygen.
E N D
Democritus • Atoms Exist
Dalton • There are different kinds of Atoms For example: Gold is made of gold atoms Iron is made of iron atoms • Some atoms form compounds • For example: • Water is made of hydrogen and oxygen atoms
Thomson • Discovered first subatomic particle: The Electron
Rutherford • Discovered the Proton
Bohr • Developed the model we will use in class: Solar System-like • Different electron orbitals have different energy levels
