Shielding effect
In chemistry, the shielding effect, sometimes referred to as atomic shielding, screening effect, or electron shielding, describes the phenomenon where inner-core electrons repel outer electrons, reducing the net attraction exerted by the nucleus. The shielding effect can be defined as a reduction in the effective nuclear charge experienced by electrons in outer shells. It is a special case of electrostatic screening in atomic physics. This effect is also significant in various fields of materials science.
