Which of the following describes a property of an atom's nucleus and a possible application of that property?

• The nucleus of an atom contains a small number of low-energy bonds. Increasing the number of bonds increases the energy within the nucleus, which, when released, can be used to generate power.

• The nucleus of a stable atom contains a specific number of protons and neutrons. Removing one or more protons from the nucleus can render an atom radioactive, which makes it useful for diagnostic imaging applications.

• The nucleus of an atom contains a large amount of stored energy. If bonds in the nucleus are broken, the stored energy is released and can be used to generate power.

• The nucleus of a stable atom contains a specific number of protons and neutrons. Adding one or more protons to the nucleus can render an atom radioactive, which makes it useful for diagnostic imaging applications.
