First-principle calculations within the density-functional theory framework are used to study the effect of high electronegativity atoms on decay rate of the Be7 nucleus. In this study, the electron-capture decay rate of the Be7 nucleus is investigated in Be(OH)2, BeF2, BeF3, BeF4, BeCl2, BeCl3, BeCl4, C36, and C60 species. It was found that the more decrease of the Be7 decay rate was estimated in the BeF4 (2.04%) and BeCl4 (1.99%) relative to the Be metal. Furthermore, the half-life of Be7 is different in various positions within C36 and C60. The Be7 half-life in Be7@C36 is greater than that in other fullerene compounds investigated, while the Be7 half-life inside C60 is smaller.
