The shielding effect is the effect where the core electrons i.e. the electrons close to the nucleus block the valence electrons from the nuclear charge of the nucleus. This effect describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. These electrons are not as strongly bonded to the nucleus as electrons closer to the nucleus. It is also referred to as the screening effect.
