TEA [102]

Explanation:

Scientist                   Evidence                                 Model

Dalton                        Gases                       indivisible, solid and spheres

J.J Thomson          Deflected beam        Negative charges evenly scattered

                                                                  through positively charged mass of

                                                                  matter.

Rutherford     Deflection of alpha            atomic model

                       particles passing                

                       through the gold foil              

The emboldened words are the answer.

  • John Dalton proposed the first model of the atoms by his works on gases. He postulated the Dalton's law of partial pressure.
  • He suggested that gases are made of tiny particles called atoms.

  • J.J Thomson proposed the plum pudding model of the atom in which the charges are evenly scattered through the positively charged mass of matter.

  • The gold foil experiment by Rutherford brought the atomic model of the atoms in the front-light.
  • The model suggests a small positively charged center which the mass of the atom.
  • The outer space is occupied by the electrons.
