Large nuclei like uranium are radioactive because
A. they are too large for the strong force to counteract electrostatic repulsion.
B. none of the above
C. they have too much mass.
D. they can hold extra particles, such as beta rays.
E. there are too many protons.

Large nuclei like uranium are radioactive because their size causes the strong nuclear force to be insufficient to counteract the electrostatic repulsion among protons. This imbalance leads to instability within the nucleus. Specifically, when large nuclei cannot maintain stability, they undergo radioactive decay. ;
