Quarter 2 - FINAL GAME QUIZ

The Fundamental Force that is holding the nucleus of an atom.

• Strong nuclear force
• Weak nuclear force
• Electromagnetic force
• Gravitational force

Why does larger nucleus emit radiation?

• Larger nuclei emit radiation due to instability from an imbalance of forces within the nucleus.
• Larger nuclei emit radiation to attract more neutrons.
• Larger nuclei emit radiation to gain energy.
• Larger nuclei emit radiation because they are heavier.
