The reduction in the force of attraction between the nucleus and the valance electrons by the electrons present in the inner subshells is called shielding effect.
As you move from top to bottom in a group number of electronic shells increase so the number of electrons in the inner shells also increases. As a result shielding effct increases.
Therefore Na will have higher shielding effect than Li as it comes after Li in the group.

Which atom has higher shielding effect Li or Na?
Na have higher shielding effect than Li *According to my chemistry book
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..
Is Li have the smallest ionic radius?
No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.
Which has a larger atomic radius sodium or cesium?
No. Lithium and sodium are both from the same column of the periodic table and so have similar chemical properties. Lithium is atomic number 3 with a weight of 6.94. Sodium is much bigger and heavier with an atomic number of 11 and a weight of 22.99.
Why LiF is not polar covalent?
The electronegativity difference of 3.0 indicates an ionic bond rather than a polar covalent. However LiF is not very soluble, like other Li salts. This is due to a partial covalent character in the bond due to the high polarising power of the small Li+ ion which distorts the electron cloud round the anion. The extent of this effect caused by cations is predicted in "Fajan's Rules"

Are mcVolt Li-Ion laptop batteries really better than NiMh and NiCd batteries?
Nickel Cadmium batteries contain Cadmium, a toxic heavy metal, which is harmful to the environment. Nickel-Metal Hydride batteries offer a higher capacity(runtime)per same size(voltage output) than NiCd batteries and mcVolt Litium Ion laptop batteries have a higher capacity than NiMh(those sold by most manufacturers). NiMh batteries are also lighter and have little memory effect compared to their NiCd counterparts. mcVolt Li-ion laptop batteries are light, have a higher capacity and have no memory effect compared to NiMh and NiCd batteries.

Sue and 3 friends scored 90 86 89 94 and 100 on a test Sue scored higher than Mike Juan scored 3 points higher than Li Ellen scored the highest What was Sue's score?
Ellen-100, Mike-90, Juan-89, Li-86 and Sue's score is 94
Why LiCl is more covalent than NaCl?
It is a small difference between the electronegativity of lithium (o,98) and sodium (0,93) - for Li the value is higher.
Li or Ca2 which cation is smaller?
Li+ is smaller than Ca2+
Which has a higher melting point LiF or MgF2?
MgF2 is higher that LiF do to the greater bond strength in MgF2. This greater strength is indicated by the charge of Mg (+3) which is higher than the +2 charge of Li. Also the MgF2 is larger in mass.
Is the atomic radius for Ne higher for Li?
Lithium is significantly larger.
What is better battery, NIMH battery or LI?
LI is better. And also NIMH does not have enough power as LI. LI is very powerful and will last longer than LI. LI is better in many things so it will work.
Is anyone better than Jet Li?
Mr. Li is 50 years old.
Is Li have the smallest ionic radius?
No, H+ ions are the smallest (proton size), hydrogen atoms and even Li+ ions are smaller than Li atoms.
