Rutherford theory of the atom
WebMar 28, 2024 · Rutherford’s atomic theory was that an atom had a central positive nucleus with negative electrons orbiting it. He developed this theory with his gold foil experiment. Ernest Rutherford’s gold foil experiment involved a particle emitter, a round detecting screen with a slit in it and a slip of gold foil in the middle.
