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.
What else can I help you with?
Which atom has higher shielding effect Li or Na?
Na have higher shielding effect than Li *According to my chemistry book
Which element has a greater ionization out of Li and O?
Oxygen has a greater ionization energy than lithium. This is because oxygen has a stronger nuclear charge and more electron shielding compared to lithium, making it more difficult to remove an electron from an oxygen atom.
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 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 atom has higher shielding effect Li or Na?
Na have higher shielding effect than Li *According to my chemistry book
Which atom has higher shielding effect Li or Be?
Lithium (Li) has a higher shielding effect compared to beryllium (Be). This is because Li has fewer protons in its nucleus than Be, leading to a weaker effective nuclear charge experienced by the outermost electrons. As a result, the inner electrons in Li can shield the outer electrons more effectively. Consequently, the shielding effect is generally stronger in elements with fewer protons when comparing atoms in the same group.
Which atom has higher shielding effect Li and Na and why?
Sodium (Na) has a higher shielding effect than lithium (Li) because it has more electron shells. The increased distance of the outer electrons from the nucleus in Na leads to greater shielding from the positive charge of the nucleus by the inner electrons. This results in a more significant reduction of the effective nuclear charge experienced by the outermost electrons in Na compared to Li. Therefore, the shielding effect increases with the number of electron shells.
Which atom has higher shielding effect Li or Na AND why?
Sodium (Na) has a higher shielding effect than lithium (Li) because it has more electron shells. As the number of electron shells increases, the inner electrons effectively shield the outer electrons from the full charge of the nucleus, reducing the effective nuclear charge experienced by the outermost electrons. In Na, there are three electron shells compared to Li's two, leading to increased electron-electron repulsion and greater shielding. This results in Na having a weaker attraction between its nucleus and valence electrons compared to Li.
Why is Li smaller than Li?
It seems there's a typo in your question, as it compares lithium (Li) to itself. If you meant to compare lithium (Li) with another element, such as sodium (Na), lithium is smaller due to its higher effective nuclear charge and fewer electron shells, resulting in a stronger attraction between the nucleus and its electrons. This leads to a smaller atomic radius compared to larger elements with more electron shells, which experience greater electron shielding.
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 is there a decrease in radius from Li to Li and to Li2?
The decrease in radius from Li to Li and then to Li₂ can be attributed to the increasing effective nuclear charge experienced by the electrons. In lithium (Li), the single electron in the outer shell experiences minimal shielding from the inner electrons, leading to a larger atomic radius. However, when lithium forms Li₂, the two lithium atoms share electrons in a covalent bond, resulting in a stronger attraction between the nuclei and the shared electrons, which pulls the electron cloud closer and decreases the overall radius.
Li or Ca2 which cation is smaller?
Li+ is smaller than Ca2+
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.
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.
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.
