"Plum pudding" model of an atom was proposed by

Options

  1. A(c)V. Raman
  2. BN. Bohr
  3. CE. Rutherford
  4. DJ.J. Thomson

Correct answer

D. J.J. Thomson

Step-by-step solution

J. J. Thomson gave the first ideal regarding structure of atom. According to him, "an atom is a solid sphere in which entire positive charge is distributed and negative charge or electrons are embedded like seeds in watermelon." It is also called plum pudding model of an atom.
