As we know from rutherford's model of atom-

A highly concentrated positive charge at the center of an atom caused an electrostatic repulsion of the particles strong enough to bounce them back to their source.

Rutherford drew the conclusion that since the dense alpha particles could be deflected by the central core, it shows that almost the entire mass of the atom is concentrated there. Rutherford named it the “nucleus” after performing the experiment in various gases. 

Hence 2 is the correct option.
