Solution
The correct option is B
the mass and positive charge of an atom are concentrated in the nucleus Rutherford’s alpha-particle scattering experiment led to the conclusion that the mass and positive charge of an atom are concentrated in the nucleus. It is assumed that when an alpha particle strikes an atom it gets deflected back due to the presence of a certain positive charge inside the nucleus and the nucleus is located at the centre of the atom. The mass of the nucleus is also responsible for the deflection.
