Introduction
Everything in universe consists of atoms. And even these so little particles have energy, actually more of it than we can imagine. This is where we come to the nuclear physics.
This is going to be a small insight in nuclear physics basics. Get to know what it means and how it works! Click ''play'' and get to know more!

Task
You will watch a video and then have a little test. Pay attention and answer according to the video, don't forget to enjoy!
Process
Questions:
- Which two forces explains nuclear physics?
- Of what consists the nucleus of atoms?
- How are they called together?
- What the atomic number describes?
- Which element atomic number is 6?
- What are called the isotopes?
- How much is the unified atomic mass unit?
- Total mass of a stable nucleus is always less/more (choose) than the total mass of the individual protons ad neutrons put together.
- What does the difference in mass is equal to?
- Which formula explains the energy?
- What are the 3 groups of a radioactivity?
Evaluation
Answers:
- Transmutation and radioactive decay
- Protons and neutrons
- Nucleons
- Number of protons
- Carbon (C)
- Elements with the same atomic number, but different mass numbers
- u=1,6605x10^-27 kg
- less
- amount of energy of the nucleus (how much energy is needed to break it to component particles)
- E=mc^2
- Alpha decay, beta decay and gamma decay
Conclusion
Now you have the basic knowledge in nuclear physics. That was very fun 10 minutes, right? But believe me, there is more!
