Rutherford atomic model| class 9

Rutherford's atomic model is called the 'planetary model of an atom'.

According to classical theory, Rutherfor'd atom model is

Atomic models have been improved over the years. Arrange the following atomic models in the order of their chronological order. (i) Rutherford's atomic model (ii) Thomson's atomic model (iii) Bohr's atomic model
