The first model of an atom was given by:A. N. BohrB. E. GoldsteinC. RutherfordD. J.J. Thomson

Answer»

J.J. Thomson proposed the first model of the atom to be similar to that of a
Christmas pudding. On the basis of Thomson’s model of an atom, an atom consists of
an electrically positively charged sphere in which negative charges are embedded. The magnitude of the positive and negative charges is equal and hence, the atom as a
whole is electrically neutral.
