The bigger the atom, the larger the number of electrons between the outermost energy level and the positively charged nucleus. As a result, the attraction between the electrons in the outermost energy level and the nucleus are slightly weaker, and so, the larger the atom, the greater the sheilding effect.

What is electron shielding?
•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
What is meant by screening effect?
Screening effect also known as shielding effect is when the electron in the outermost orbital faces inter electronic repulsion from the inner electrons, thus reducing the effective nucleur charge.
Why is KCl ionic while LiCl you scovalent?
Li is small atom and thus have comparatively compactly arranged electrons.. It seizes the Cl atom to take away its electron...thus it have covalent bond rather than ionic.. K is bigger in size..have weak nuclear attraction...screening and shielding effect is more in K,..therefore can form gud ionic bonds.... ok dear..
What element has the biggest shielding effect in its atom?
== == == == The screening effect, or shielding effect, is how electrons in the same atom interact with each other. In a single-electron atom (in isolation), the electron is only interacting with the proton; in a multielectron atom, the electrons are both interacting with the proton(s), but also with each other. While electrons are attracted to the protons in the nucleus, they are repelled by the other electrons. This electron-electron repulsion decreases the attractive force of the protons on the electrons.The shielding effect changes the effective nuclear charge -- effectively decreasing the true nuclear charge. This effect causes atoms to get smaller as you across a period (row) of the periodic table, as well as many other periodic trends observed in the periodic table.See the Web Links and Related Questions for more information about shielding and periodic trends.--------------------------------------------------------------------------- keep in mind that different orbitals have varying shielding effciencies depending on their shape and symmetry from greatest effect to least s>p>d>f and the effective nuclear charge can be estimated with good approx. by the Slater's Rule whereZ_eff=Z-S Z_eff= effective nuclear charge Z=nuclear charge S=screening (or shielding) factorthe screening factor is calculated by following the directions given at this websitehttp://intro.chem.okstate.edu/WorkshopFolder/SlaterRule.html
Is an oxygen atom bigger than a hydrogen atom?
An oxygen atom has 8 of each neutrons, electrons, and protons. While a carbon atom has only 6 of each. I had the same problem! So i hope this helped :)
Why does the bigger size atoms have more shielding effect give short answer?
Because they have many electron shells.
Is shielding effect more noticeable on metals or non-metals?
in metals due to shielding effect ionization value is low

Why does bigger size atom have low ionization energy?
It is " bigger " because it has more electrons in orbit around it. So, to keep things simple and away from such concepts as shielding, we know that the farther electrons are from the nucleus the looser they are held and to ionize this element is easier, thus lower ionization energy needed.

What is shielding materials?
it prevents surrrounding magnetic field reaching the sensitive area of a piece of an equipment whose operation may be affected by the fields. magnetic shielding can address the problem of the damage of electronic equipment because of a great magnetic field like cell phones and computers
Why The bigger the atom have low ionization energy?
it is bigger..so it has more electron in orbit than smaller atom...so it keep simple
Why is bigger circle used to represent an atom of uranium?
because it has more electrons
How does cc effect a dirt bike?
Bigger cc = bigger motor = more power. But also heavier bike.
Why is a bigger circle is used to represent an atom of Uranium?
because it has more electrons
