Effective nuclear charge for helium - Brainly.in

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. Web30 okt. 2024 · $\begingroup$ No, it is not true. If it were, the electron energy levels of helium and hydrogen would be the same. However, it is true that in multi-electron atoms (neutral or otherwise) you have to take into account the 'shielding' of the nuclear charge by the other electrons. thibaut lacaze kineWebElectrons in the _____ subshell experience the lowest effective nuclear charge. 5p.
