Which of the following is not a conclusion from the Rutherford's alpha scattering experiment?
The size of a nucleus is very small as compared to the size of an atom
Mass of the atom is concentrated in its orbits
The negatively charged electrons surround the nucleus of an atom
There is a positively charged center in the atom called nucleus
The correct option is B Mass of the atom is concentrated in its orbits
According to the observations from the Rutherford's alpha scattering experiment, most of the mass of the atom is concentrated at the center of the atom in a positively charged entity. Since, the rest of the space consists of orbits and this space is mostly empty, so the concentration of mass in the orbits is extremely low and insignificant as compared to the center of the atom.
