Chemistry · Bohr model of a hydrogen atom: its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model
Rutherford's alpha Scattering experiment showed that:
Rutherford's alpha Scattering experiment showed that:
- A. the atoms were smashed up by alpha particles
- B. the atoms consisted or protons in a matrix of electrons
- C. the nucleus was quite large and was positively charged
- D. the nucleus was very small and positively charged
Step-by-step solution
Rutherford's alpha scattering experiment involved firing alpha particles at a thin gold foil. Most particles passed straight through, but a few were deflected at large angles. This indicated that the atom has a small, dense, positively charged nucleus, contradicting the plum pudding model. Option D correctly states that the nucleus was very small and positively charged.
