Final answer:
The local diamagnetic shielding effect refers to the reduction in the attractive interaction between the nucleus and an electron that is farther away due to electron shielding.
Step-by-step explanation:
The local diamagnetic shielding effect in chemistry refers to the reduction in the attractive interaction between the nucleus and an electron that is farther away due to the presence of electrons closer to the nucleus. These inner-shell electrons neutralize a portion of the positive charge of the nucleus, creating a shielding effect.
For example, in the case of electron shielding, the inner electrons effectively block or shield the valence electrons in an atom from the full attractive force of the nucleus. This shielding effect results in a decrease in ionization energy, as shown in figure 6.18.2.
The local diamagnetic shielding effect is an important concept in understanding the electron arrangement and chemical properties of atoms and molecules.
