Question

The below model of organization of electrons in atom is given by ___________

(a) R. A. Millikan

(b) J. J. Thomson

(c) Rutherford

(d) Galileo

I had been asked this question at a job interview.

This intriguing question comes from Discovery of Sub-atomic Particles in section Structure of Atom of Chemistry – Class 11

Answer 1

The correct answer is (b) J. J. Thomson

To explain: Thomson proposed a model of the atom, in which electrons are embedded to make it as the stable electrostatic arrangement and such that positive charge is equally distributed around a sphere. Mass is assumed to be equally distributed. So. it has different names like plum pudding, watermelon and raisin pudding model.
