TED-ED: The 2,400-year search for the atom - Theresa Doud

The video explores the evolution of atomic theory, starting with Democritus's idea of indivisible particles called atomos. It covers John Dalton's revival of atomic theory in the 19th century, J.J. Thomson's discovery of the electron, and Ernest Rutherford's nuclear model. Niels Bohr's contributions and the development of quantum theory are also discussed, highlighting the complexity and ongoing evolution of our understanding of atoms.

What advancements did Niels Bohr make to the atomic model?

Explain the implications of Werner Heisenberg's uncertainty principle.

How does the current quantum model of the atom differ from earlier models?
