WebFeb 2, 2024 · For the first electron around the nucleus, the effective nuclear charge equals the nuclear charge: Z_\text {eff} = Z Z eff = Z. The value of Z_\text {eff} Z eff then decreases approaching 1 1 for an infinite distance from the nucleus. This is the value of the potential energy experienced by the last electron added to the shell Remember that it ... WebDensity-functional theory with generalized gradient approximation for the exchange-correlation potential has been used to calculate the global equilibrium geometries and electronic structure of neutral, cationic, and anionic aluminum clusters containing up to 15 atoms. The total energies of these clusters are then used to study the evolution of their …
