The first atomic model of the atom was discovered by
- Dalton
- Rutherford
- J.J. Thomson
- Bohr’s
The correct answer is: J.J. Thomson
In 1898, J. J. Thomson proposed the first of many atomic models to come. He proposed that an atom is shaped like a sphere with a radius of approximately 10-10m, where the positive charge is uniformly distributed. The electrons are embedded in this sphere so as to give the most stable electrostatic arrangement.
