Question

Write balanced nuclear equations for the following:(a) β⁻decay of sodium-26

Answer 1

The balanced nuclear equations for the following:(a) β⁻decay of sodium-26 is Na²⁶₁₁ → Mg²⁶₁₂ + β₋₁⁰ + energy.

What is beta decay?

Beta decay (-decay) is a type of radioactive decay in nuclear physics in which a beta particle (fast energetic electron or positron) is ejected from an atomic nucleus, converting the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron converts it into a proton by the emission of an electron accompanied by an antineutrino; or positron emission converts a proton into a neutron via the emission of a positron accompanied by a neutrino. The beta particle and its accompanying (anti-)neutrino do not exist in the nucleus before beta decay, but are generated during the decay process. Unstable atoms gain a more stable proton-neutron ratio through this process.
