Could anyone give me a couple of sentences to what it is?

Electron screening in atoms refers to the phenomenon where the outer electrons of an atom shield the nucleus from the full charge of the protons, resulting in a weaker attractive force between the nucleus and the outer electrons. This effect is also known as shielding or screening by electrons.
Electron screening plays a crucial role in understanding the properties and behavior of atoms, as it affects the energy levels and interactions between electrons and the nucleus. It also helps explain various phenomena, such as the stability of atoms, ionization energy, and atomic size.
Electron screening causes the effective nuclear charge to be lower than the actual charge of the nucleus, resulting in a decrease in the attraction between the nucleus and outer electrons. This, in turn, affects the arrangement of electrons in energy levels and sublevels, as well as the overall size of the atom.
The degree of electron screening in atoms is influenced by the number of electrons, their energy levels and sublevels, and the distance between the nucleus and outer electrons. It is also affected by factors such as atomic number, shielding constant, and the nuclear charge.
Yes, electron screening can be observed experimentally through various techniques such as atomic spectroscopy, which measures the energy levels of electrons in atoms. The degree of screening can also be calculated using mathematical equations based on experimental data.
