Nuclear Physics

2. defect – The “missing” mass when a nucleus forms, converted into binding energy.
4. – The collective name for protons and neutrons in the nucleus.
8. – Atoms of the same element with different numbers of neutrons.
9. – Radiation involving an electron or positron being emitted from the nucleus.
12. – Dense core of the atom, containing protons and neutrons.
13. number – The number of protons in the nucleus of an atom.
14. – The fundamental force responsible for beta decay.
16. – The process by which an unstable nucleus breaks down and emits radiation.
18. particle – A particle that cannot be divided into smaller components (e.g., quarks, electrons).
19. – The antimatter particle of the electron, with a positive charge.
20. – Type of radiation that has enough energy to remove electrons from atoms.
22. – High-energy electromagnetic radiation emitted from the nucleus.

1. – Describes a substance that spontaneously emits radiation.
3. – The fundamental force that binds protons and neutrons together in the nucleus.
5. – Distinct kinds of atoms defined by their numbers of protons and neutrons.
6. – First name of the scientist linked to the radiation counter that clicks when detecting particles.
7. – Positively charged particle in the nucleus.
10. – Type of radiation made of two protons and two neutrons.
11. – Describes the four basic forces of nature.
15. – Negatively charged particle orbiting the nucleus.
17. – Neutral particle found in the nucleus of an atom.
21. – Refers to the processes and forces that occur inside the atomic nucleus.
