Beta particle is a neutron that splits into a proton and an electron.
Energy released is gamma rays (Electromagnetic spectrum)
Atomic mass stays the same but the atomic number increases by one because a new proton is made from the neutron.
This creates an isotope of the new element since it doesn’t have the right number of neutrons in the nucleus.
Radioactive Decay – Gamma Decay:
Gamma decay releases energy as a gamma ray (Electromagnetic spectrum) or photon.
No particles (protons, neutrons, or electrons) are released.
Uses of Radioactive Decay – Gamma Rays:
Radioactive decay is used in many ways: smoke detectors, sterilize bandages, test the thickness of metal sheets, find leaks in pipes, find the age of fossils, artifacts, rocks, bones, cloth, and the age of paints or canvases, and to find and treat diseases.
A nuclear fission is a reaction where a large, unstable nucleus (has too many protons and neutrons) breaks down into two smaller nuclei.
The smaller nuclei are more stable but can still break down into smaller nuclei through nuclear fission.
Creates 2 smaller atoms and releases 3 neutrons.
Fission happens naturally with larger elements.
Nuclear Chain Reaction:
Nuclear chain reactions give off huge amounts of energy very quickly.
Controlled reactions turn the energy released into electrical energy, like what we use in nuclear power plants.
Uncontrolled reactions are what is used in atomic bombs.
Advantages and Disadvantages of Nuclear Power Plants:
Produces (makes) large amounts of energy from small amounts of energy.
Cost of fuel is less so the electricity made costs less.
