Helium effective nuclear charge

Webwhere is effective nuclear charge number seen by each electron. Let us recalculate the ground-state energy of helium as a function of , using the above trial wavefunction, and then minimizethe result with respect to . According to the variational principle, this should give us an even better estimate for the ground-state energy.

Web12 dec. 2024 · We know that oxygen has 2 core electrons, and 8 protons, therefore, it’s effective charge is 6 (8 - 2). The valence electrons feel this +6 charge (hence why there are 6 valence electrons). However, those valence electrons don’t contribute to the electron shield. And that means electrons outside of the atom can feel that charge too.
