As an atom's nucleus gets larger the electric charges repelling the protons get larger. to compensate for this greater electric charge the atom

As an atom's nucleus gets larger the electric charges repelling the protons get larger. To compensate for this greater electric charge the atom

A)needs more neutrons to gain enough nuclear binding forces to overcome the repulsion.  

B)needs fewer neutrons to gain enough nuclear binding forces to overcome the repulsion.  

C)needs more electrons to gain enough nuclear binding forces to overcome the repulsion.  

D)needs fewer neutrons to gain enough nuclear binding forces to overcome the repulsion.

The answer is A)needs more neutrons to gain enough nuclear binding forces to overcome the repulsion.
