•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.
Also, it has trends in the Periodic Table

∙ 10y agoThe 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.

∙ 11y agoShielded 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.

In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding decreases the effective nuclear charge.
The addition of electron shells results in?
The addition of electron shells results in more shielding of electrons from the nucleus.
The fewer electron shells the shielding of electrons from the nucleus.?
less
An electron in an orbital that penetrates closer to the nucleus will always experience more shielding than an electron in an orbital that does not penetrate as far?
False
What causes the sheilding effect to remain constant across a period?
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.
Why is electron shielding not a factor when you examine a trend across a period?
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.
In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding decreases the effective nuclear charge.
The attraction of the nucleus for the outer electrons in large atoms is lessened as a result of?
Its all called electron shielding.
What is the shielding effect trend?
The reduction in the force of attraction between the nucleus and outer most electron is known as shielding effect
Do all of the noble gases have at least 3 electron shielding layers?
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?
The addition of electron shells results in more shielding of electrons from the nucleus.
In which orbital does an electron in a phosphorus atom experience the greatest shielding?
1s
How many shielding atoms does magnesium have?
Magnesium has 3 electron shells.
The fewer electron shells the shielding of electrons from the nucleus.?
less
What does electron shielding most affects?
It had most effect on outer shell electrons.
An electron in an orbital that penetrates closer to the nucleus will always experience more shielding than an electron in an orbital that does not penetrate as far?
False
Why does the bigger size atoms have more shielding effect give short answer?
Because they have many electron shells.
