Jan 15, 2019 · Express the changes in the atomic number and mass number of a radioactive nuclei when an alpha, beta, or gamma particle is emitted. Write nuclear equations for alpha and beta decay reactions.
Oct 27, 2022 · Alpha (\(α\)) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay: \[\ce{^{210}_{84}Po ^4_2He + ^{206}_{82}Pb} \hspace{40px}\ce{or}\hspace{40px} \ce{^{210}_{84}Po ^4_2α + ^{206}_{82}Pb}\nonumber \] Alpha decay occurs primarily in heavy nuclei (A > 200, Z > 83).

Feb 20, 2022 · In alpha decay, a \ (\ce {^4He}\) nucleus simply breaks away from the parent nucleus, leaving a daughter with two fewer protons and two fewer neutrons than the parent (Figure \ (\PageIndex {2}\)). One example of \ (\alpha\) decay is shown in Figure \ (\PageIndex {2}\) for \ (\ce {^ {238}U}\).
So we can actually write down a chemical reaction equation for alpha decay: Ra → Rn + He 2 + The radium nucleus (Ra, atomic number 88) breaks up into the helium nucleus (He 2 + , the little chunk) and a daughter nucleus that corresponds to the element radon (Rn, atomic number 86).

How does beta decay affect the atomic number of a nucleus?
This decay, or loss of energy, results in an atom of one type, called the parent nuclide, transforming to an atom of a different type, named the daughter nuclide. The three principal modes of decay are called the alpha, beta and gamma decays.
