Question

What conditions in the nucleus are likely to result in an atom that is unstable?

A. When the attraction of the electrostatic force is greater than the
repulsion of the strong force
B. When the repulsion of the electrostatic force is greater than the
attraction of the strong force
C. When the attraction of the electrostatic force is greater than the
attraction of the strong force
D. When the repulsion of the electrostatic force is weaker than the
repulsion of the strong force

Answer 1

Answer is D just to clarify hope I could help

Answer 2

Answer: D. When the attraction of the strong force is weaker than the repulsion of the electrostatic force

Step-by-step explanation: An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom's nucleus may result from an excess of either neutrons or protons.
