Experts are tested by Chegg as specialists in their subject area. The concept of electron shielding, in which intervening electrons act to reduce the positive nuclear charge experienced by an electron, allows the use of hydrogen-like orbitals and an effective nuclear charge (\(Z_{eff}\)) to describe electron distributions in more complex atoms or ions. Numerous permanent and temporary particles exist in the atom. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. However, the 2s electron has a lower shielding constant (\(S<1\) because it can penetrate close to the nucleus in the small area of electron density within the first spherical node (Figure \(\PageIndex{3}\); green curve). How Many Core And Valence Electrons Does I Have? Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z 1) negative electrons in the atom.
