Explanation
The total number of atoms neither remains constant (as in option (a) nor can ever increase (as in option (b) and (c)).
They will continuously decrease with time. Therefore option (d) is correct.
Charge density is uniform inside and then falls rapidly near the surface of the nucleus
1st reaction is fusion and 4th reaction is fission.
The given reaction is a nuclear reaction, which can take place only if a proton (a hydrogen nucleus) comes into contact with a lithium nucleus. If the hydrogen is in the atomic from, the interaction between it’s electron cloud and the electron cloud of a lithium atom keeps the two nuclei from getting close to each other. Even if isolated protons are used, they must be fired at the Li atom with enough kinetic energy to overcome the electric repulsion between the proton and Li atom.
Rutherford confirmed that the repulsive force on α-particle due to nucleus varies with distance according to inverse square law and that the positive charges are concentrated at the centre and not distributed throughout the atom
