Synthesis of new elements with 
is currently a forefront issue in modern nuclear physics. The central question then arises as to the stability and decay properties of these new elements. In this study, the competition between 
-decay, spontaneous fission, cluster radioactivity, and 
-decay in the isotopic chains of and was investigated using the finite-range droplet model (FRDM) and Weizsäcker -Skyrme model (WS4). The Royer formula, Karpov formula, Universal Decay Law, and Sobhani formula were applied to analyze each respective decay mode. It was found that cluster radioactivity and -decay is at a disadvantage in these isotopic chains, with -decay and SF being the dominant decay modes. For nuclei with longer half-lives for the dominant decay modes, -decay tends to be the most prevalent. 
is a candidate for the neutron magic number based on WS4 and FRDM. In addition, the generalized liquid drop model with corrections for surface diffuseness effects was employed to study -decay across four different sets of mass models: FRDM, WS4, Koura–Tachibana–Uno–Yamada (KTUY) mass formula, and Niu2022. The calculation of -decay half-lives was further optimized through the use of the radial basis function network.
