- Radioactivity
- Radioactive Nuclei
- Chemical change
- Bonds between 2 atoms are broken and new bonds are formed, Nuclei stay the same
- Nuclear change
- New atoms of different elements are formed
- Because the Nuclei change
- New atoms of different elements are formed
- Chemical change
- Radioactive Materials
- Some atoms are stable, others are not in which case they are unbalanced
- They want to become stable
- In doing so they emit radiation energy or particles (aka radioactivity)
- Radioactive Decay
- Breaking up process
- Atomic Nucleus of an unstable atom loses energy by emitting ionising Radiation
- RANDOM PROCESS
- Background Radiation
- There is always a small amount of radiation around us due to radioactive particles in the environment
- Comes from many sources
- Can be measured using a Geiger-Muller tube/counter
- At high altitudes it increases because of more exposure to cosmic rays (sunrays)
- Underground in mines it increases due to the surrounding rocks (depends on rock type)
- Radioactive Nuclei
- Radioisotopes- Radioactive Isotopes
