Abstract: Radon gas, a colourless, odourless radioactive gas from uranium, is of increasing interest due to its health and environmental impact, and its potential use in renewable energy. The study investigated the shapes of radon element even-even nuclei, which included studying the deformation parameters in two ways, the first β derived from the value of the electrical transition probability B(E2). The highest value was at atomic mass number (228) by (0.2643) and the lowest value at atomic mass number (212) by (0.0620). The second method involved determining the deformation parameters (δ) based on the value of the electric quadruple moment (Q_o), where the highest value was (0.2121) and the lowest value was (0.0495) at atomic mass numbers (228) and (212) respectively. Additionally, the root mean square of the radius (r) was calculated. The research indicates that even-even nucleons have spherical shapes and small deformation, while those near a magic number have flat or elliptical shapes.

Keywords: radon; root mean square; deformation parameters.
