development of the model of the atom

• how did alpha particle scattering experiment lead to nuclear model from plum pudding model?

  • alpha particles directed at gold foil
  • most alpha particles pass through so most of the atom is empty space
  • few alpha particles deflected so mass is concentrated in the nucleus and the nucleus is positively charged
  • plum pudding was wrong as mass was spread throughout the atom & it was a ball of positive charge
