Radioactivity
Cards in this deck (10)
- 1Radioactive atomsAtoms that are not stable and change form over time
- 2Radioactive DecayWhen ratio of neutrons:protons is to high, and unessary matter is release to form a more stable isotope.
- 3RadiationMatter released from an atom during radioactive decay
- 4Why does radiation occur?To create a more stable nuclei by releasing unessecary matter
- 5Background radiationRadiation that exist all around us from various sources.
