Answer:
Rutherford's experiment led to the rejection of JJ Thomson's raisin bundle model. In the experiment, a thin gold strip was bombarded with alpha particles. According to Thomson's atomic model, all alpha particles should have passed through the strip, but in this experiment it was found that some of the particles were reflected backwards. Based on his experiment, Rutherford published the result that almost the entire mass of an atom is concentrated in its nucleus. Rutherford's atomic model was later improved by Niels Bohr, who published the Bohr model.
In an electrically neutral Atom of element number 44, or atomic number 44, there would be also 44 electrons, as the net charge of the subatomic particles, protons and electrons would be zero.
