Nuclear Band of Stability

Nuclear Band of Stability

Radioisotopes Radioisotopes Atoms with unstable nuclei. The ratio of protons-to-neutrons is not adequate for nuclear stability. Most elements need more neutrons than protons to maintain stability within the nucleus. (see band of stability graph).

Atomic Forces Electrostatic Forces : Forces between charged particles. Types of electrostatic forces: Attractive: (p+ and e-) Repulsion: (p+ and p+ e- and e-) Nuclear Forces: Forces that holds p+ and n0 together in nucleus. Nucear forces > Electrostatic forces

Nuclear Reactions Synonyms: Radioactive Decay; Radioactivity A reaction that occurs within the nucleus of a radioisotope in order to stabilize it. Spontaneous Reactions Reaction that occurs on its own without any outside help.
