On the basis of these observations, Rutherford explains that the positive charge of the gold atom's nucleus is weak and spread out over a wide area. Thus, the correct option is A.
The major drawback of Rutherford's model is that it failed to explain the stability of electrons in a circular path. The orbital revolution of electrons around the nucleus is found to be unstable.
