De Broglie

Answer 1

Dalton: Suggested that atoms can't be destroyed nor created and that they were unbreakable.

Thomson: The plum pudding model: The idea that the atom was a large positive particle with electrons in a rotating ring... he discovered the electron as well.

Rutherford: The planetary model: that proteins acted like a sun, and the electrons acted like planets orbiting the sun.

Niels Bohr: The Bohr model: incorporated quantum theory into Rutherford's model

Louis-Victor De Broglie: Suggested that subatomic particles can behave like waves especially the electron as he worked with.
