1. The alpha particles in Rutherford's experiment were helium nuclei, each consisting of two protons and two neutrons. They were emitted from a radioactive source with high energy and positively charged.

  2. Ernest Rutherford's objective in his experiment involving alpha particles and gold foil was to investigate the structure of the atom by studying how alpha particles interacted with the atoms of the gold foil.

  3. Thomson's atomic model, proposed in 1904, suggested that atoms resemble a "plum pudding," where negatively charged electrons are embedded within a positively charged sphere, akin to raisins within a pudding, thus implying that atoms are overall electrically neutral.

  4. In Thomson's model of the atom, electrons were depicted as negatively charged particles embedded within a positively charged sphere, analogous to raisins (electrons) embedded in a positively charged "plum pudding" (the rest of the atom).
