What is screening effect ?
Answers
Answer:
Screening Effect Definition:
The screening impact is likewise called the defensive impact. The phenomenon takes place while the nucleus reduces its pressure of enchantment at the valence electrons because of the presence of electrons withinside the internal shell. This is called a screening impact. Outer electrons enjoy enchantment from the nucleus and repulsion from the internal electrons. As the enchantment among the nucleus decreases, the repulsion will increase among the internal electrons and outer electrons.
The defensive impact is likewise described because the discount with inside the powerful nuclear price at the electron cloud. It is a unique kind of electric powered discipline screening.
The wider the electron shells with inside the space, the weaker the digital interplay among the electron and the nucleus because of the screening.
Higher is the nuclear pressure of attractions, extra is the ionization enthalpy required. Thus, the screening impact is inversely proportional to ionization enthalpy.
In general, the screening impact with inside the shells is: s>p>d>f
The screening impact is likewise called the "defensive impact". If the electron shells are wider in space, the interplay among the nucleus and electrons reduces. The order of screening impact with inside the shells is as follows: s > p > d > f. Nuclear fission is one of the high-quality examples of the screening impact.

Answer:
The phenomenon of the inner shell electrons reducing the nucleus's force of attraction on the outermost valence electrons is known as the screening effect or shielding effect.
Explanation:
The phenomenon of the inner shell electrons reducing the nucleus's force of attraction on the outermost valence electrons is known as the screening effect or shielding effect.The more inner electrons there are, the more they protect the outermost electron from the nucleus, freeing it from any nuclear pull.The "shielding effect" is another name for the screening effect.
The interaction between the nucleus and the electrons decreases as the electron shells are wider in space.The screening effect in the shells occurs in the following order: s > p > d > f.One of the greatest instances of the screening effect is nuclear fission.
