What is beta plus (β⁺) decay? Beta plus (β⁺) decay, also known as positron emission, is a type of radioactive decay in which a proton inside an unstable nucleus is converted into a neutron, with the emission of a positron…
What is beta minus (β⁻) decay? Beta minus (β⁻) decay is a type of radioactive decay in which a neutron inside an unstable nucleus is converted into a proton, with the emission of an electron (the beta particle) and an…
What is radioactive decay? Radioactive decay is the spontaneous transformation of an unstable atomic nucleus into a more stable configuration, accompanied by the emission of radiation. This process occurs because the original nucleus has an imbalance of forces or an…
What is mass defect and how does it relate to E = mc2? Mass defect is the difference between the combined mass of a nucleus’s individual protons and neutrons and the actual measured mass of the bound nucleus. The bound…
What is binding energy per nucleon and why is it important? Binding energy per nucleon is the average amount of energy required to remove a single proton or neutron from a nucleus. It is calculated by dividing the total nuclear…
What is nuclear binding energy? Nuclear binding energy is the energy required to completely separate a nucleus into its individual protons and neutrons. It represents how strongly the nucleons are held together by the strong nuclear force. The greater the…
What is the band of stability? The band of stability is a graphical representation of stable nuclei plotted according to their number of protons (Z) and neutrons (N). When neutron number is plotted against proton number, stable nuclei fall within…
What determines nuclear stability? Nuclear stability is determined by the balance between two opposing forces within the atomic nucleus: the strong nuclear force, which binds protons and neutrons together, and the electrostatic repulsion between positively charged protons, which pushes them…
