Chemistry · Bohr model of a hydrogen atom: its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model
How would you describe J.J. Thomsons model of the atom?
How would you describe J.J. Thomsons model of the atom?
- A. \) An atom is indivisible
- B. The atom is composed of only negatively charged particles.
- C. The atom is composed of a positive core with negatively charged particles orbiting the positive core.
- D. The atom is composed of diffused ball of positive charge with negative particles dispersed throughout.
Step-by-step solution
J.J. Thomson's model, known as the 'plum pudding' model, proposed that the atom is a sphere of uniform positive charge with negatively charged electrons embedded within it, like plums in a pudding. This was based on his discovery of the electron and the need for overall charge neutrality.
