In [[chemistry]], the '''shielding effect''' sometimes referred to as '''atomic shielding''' or 
'''electron shielding''' describes the attraction between an [[electron]] and the [[Atomic nucleus|nucleus]] in any atom with more than one [[electron]]. The shielding effect can be defined as a reduction in the [[effective nuclear charge]] on the electron cloud, due
to a difference in the attraction forces on the electrons in the atom. It is a special case of  [[electric-field screening]].
This effect also has some significance in many projects in material sciences.
