Study Notes
Importance of Nuclear Physics
- Studying nuclear physics is crucial for humans, but its significance is often questioned.
Nucleus Composition
- The symbol Al refers to the aluminum nucleus.
- The number of neutrons (N) in the aluminum nucleus can be calculated using the relation A = Z + N, resulting in 14 neutrons.
Isotopes
- Isotopes are atoms of the same element with the same atomic number (Z) but a different atomic mass (A).
Charge of a Nucleus
- The charge of a nucleus (q) is calculated by multiplying the atomic number (Z) by the elementary charge (e): q = Z × e.
- For the 198Au nucleus, Z = 79, resulting in a charge of q = 79 × 1.6 × 10^-19 = 126.4.
Nuclear Stability
- Despite having similar charges, protons in a nucleus do not repel each other, allowing the nucleus to maintain stability and bondage.
- The reason for this stability is due to the strong nuclear force that binds nucleons (protons and neutrons) together.
Fusion Bombs
- The concept of nuclear physics is applied in the military to produce fusion bombs, such as the Hydrogen bomb.
- Fusion bombs are more fatal and lethal than fission bombs, but they are uncontrollable reactions.
