Question

If the Thomson model is considered to be correct what could be the observation of the Rutherford alpha ray scattering experiment?

Answer 1

Thomson Model of an Atom:
J.J. Thomson (1898) tried to explain the structure of the atom. He proposed that an atom consists of a sphere of positive electricity in which electrons are embedded like a plum in pudding or seeds evenly distributed in red spongy mass in the case of a watermelon.

Observations of Rutherford's alpha scattering experiments are as follows :

• There must be a large empty space within the atom.
• There must be something massive and positively charged structure present in the atom.
• The whole positive charge in the atom is concentrated in a very small space.
  

If the Thomson model is considered to be correct, the observation of the Rutherford alpha Ray scattering experiment would be

• There must be no empty space within the atom.
• There must be nothing massively charged structure present in the atom.
• The whole positive charge in the atom is not concentrated in a very small space.
