Nuclear Principles

What is the primary force that holds protons and neutrons together in the nucleus?

• Strong nuclear force

• Electromagnetic force

• Gravitational force

• Weak nuclear force

What does the equation E = mc² represent in nuclear physics?

• Mass-energy equivalence

• Nuclear stability

• Radioactive decay

• Nuclear fission

What is a characteristic of stable nuclei?

• Balanced ratio of protons to neutrons

• Imbalance in the number of protons and neutrons

• Undergoes radioactive decay

• Emits particles or energy

What happens to the mass of the nucleus during nuclear fission?

• It decreases

• It increases

• It remains the same

• It doubles

Which type of decay involves the emission of particles or energy?

• Alpha decay

• Beta decay

• Gamma decay

• All of the above
