📚 Topic Summary
The strong nuclear force is one of the four fundamental forces in nature. It's responsible for binding protons and neutrons together in the nucleus of an atom, overcoming the electrostatic repulsion between the positively charged protons. This force is incredibly strong but acts only over very short distances, approximately the size of a nucleus ($10^{-15}$ meters). Without the strong nuclear force, atoms wouldn't exist!
This lab activity explores these characteristics. We'll investigate how the range and magnitude of the strong force influence nuclear stability.

📝 Part B: Fill in the Blanks
The strong nuclear force is the _________ force in the nucleus. It acts between _________ and neutrons, overcoming the _________ repulsion of the protons. Its range is very _________, about the size of the nucleus.
🤔 Part C: Critical Thinking
Imagine the strong nuclear force suddenly disappeared. What would happen to atoms and, consequently, to everything around us? Explain your reasoning.
