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
When alpha particles are sent through a thin metal foil, most of them go straigh
When alpha particles are sent through a thin metal foil, most of them go straight through the foil because:
- A. alpha particles are much heavier than electrons
- B. alpha particles are positively charged
- C. most part of the atom is empty space
- D. alpha particles move with very high velocity
Step-by-step solution
In Rutherford's alpha particle scattering experiment, most alpha particles passed straight through the thin metal foil because atoms are mostly empty space, with the nucleus occupying a very small volume.
