"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. " - Helium effective nuclear charge

Helium contains two protons and two electrons. But there is not the effective nuclear charge equal 2 on each electron in helium atom, it is about 1.7 units. In atomic physics, the effective nuclear charge is the actual amount of positive (nuclear) charge experienced by an electron in a multi-electron atom. The term "effective" is used because the shielding effect of negatively charged electrons prevent higher energy electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner layer. The effective nuclear charge experienced by an electron is also called the core charge. It is possible to determine the …

WebAboutTranscript. An element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay. Sort by:
