•The shielding effect describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell.
•It is also referred to as the screening effect or atomic shielding.
•Shielding electrons are the electrons in the energy levels between the nucleus and the valence electrons. They are called "shielding" electrons because they "shield" the valence electrons from the force of attraction exerted by the positive charge in the nucleus.

The electron shielding effect is the effect where core electrons block valence electrons from the nuclear charge of the nucleus.
You can calculate the effective nuclear charge with:
Zeff = Z - S
where Z is the total number of protons in the element and S is the total number of core electrons (electrons that are not valence electrons).
Simply put, the shieding effect is inside electrons blocking outside electrons from getting the positive charge.
Positive and negative charges attract each other so the more effective charge the electrons get, the more attraction there is between the nucleus and the outer electrons. So as the effective nucleur charge increases, the atom and it's radii becomes smaller; so as the shielding becomes stronger, the nucleur charge decreases and the size of the atom increases.

Shielded electrons are all of the electrons in an atom that are not valence electrons. For example, a neutral argon atom has 18 electrons. Since argon is a noble gas in group 18, it has 8 valence electrons. That means that there are 10 electrons that are shielded and do not participate in chemical reactions.
Valence electrons are shielded from the nucleus by electron shells. (apex) kw<3
electron shells shield the valence electrons from the nucleus
Electron shielding is when electron shells shield the valence electrons from the positive charge in the nucleus
Electron shielding decreases the effective nuclear charge.
The addition of electron shells results in more shielding of electrons from the nucleus.

False
Electron shielding is not a factor across a period because they all have the same number of electron shells! No further (extra) shells means that they are all affected by electron shielding equally.

Its all called electron shielding.
The reduction in the force of attraction between the nucleus and outer most electron is known as shielding effect
No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.
The addition of electron shells results in more shielding of electrons from the nucleus.

Magnesium has 3 electron shells.

It had most effect on outer shell electrons.
False
Because they have many electron shells.
