Study Notes
Atomic Number
- The atomic number of an element is defined as the number of protons present in the nucleus of its atoms.
- It uniquely identifies an element and determines its position on the periodic table.
Nuclear Fission vs Nuclear Fusion
- Nuclear fission is the process where the nucleus of an atom splits into smaller parts, releasing a significant amount of energy, typically used in nuclear power plants.
- Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy, as seen in stars like the sun.
Effects of Gamma Rays
- Gamma rays are a form of high-energy electromagnetic radiation with a short wavelength.
- They can penetrate most materials and are used in medical applications like cancer treatment, but can also lead to severe biological damage due to ionization of atoms in living tissues.
Discovery of X-Rays
- X-rays were discovered by Wilhelm Conrad Röntgen while he was experimenting with Lenard tubes and Crookes tubes in 1895.
- This discovery revolutionized medical imaging and diagnostics.
Uranium-238 Decay
- When Uranium-238 decays by losing an alpha particle, it transforms into Thorium-234.
- This decay process is a part of the natural radioactive decay series of uranium.
