Effective nuclear charge of hydrogen

WebOct 25, 2024 · Electron Shielding and Effective Nuclear Charge. If an electron is far from the nucleus (i.e., if the distance \(r\) between the nucleus and the electron is large), then at any given moment, many of the other electrons will be between that electron and the nucleus (Figure \(\PageIndex{1}\)). Hence the electrons will cancel a portion of the …
