Why Na has higher shielding effect than Li?
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 is the equation to show the formation of an ion of lithium from its atom?
Correct answer:LiLiYour response:Li+Correct answer:Your response:Correct answer:Li+Li^+^Your response:Li++Correct answer:e-e^-^Your response:e+
Is Li a cation or an anion?
Li ( lithium) is an ATOM. However, when it ionises (loses) an electron it becomes the Lithium ion (Li^(+)). Positive ions are collectively named as CATIONS. Negative ions are collectively named as ANIONS. NB An atom is an UNcharged species of any element. When it becomes a charged species, then it is an ION. Cation(+) & Anion(-) .
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 is the oxidation number of Li2?
The oxidation number of Li in Li2 is +1. Each Li atom has an oxidation number of +1 in ionic compounds.
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 Na has higher shielding effect than Li?
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.
How do you write a positive Li atom and a negative Ci atom?
Li+ and Cl-
Which is donate electron for LI and CL?
Li atom donates one electron to a Cl atom when Li+Cl- is to be formed as ionic compound (salt):Li --> e- + Li+Cl + e- --> Cl--------------- +Li + Cl --> LiCl (or Li+Cl-)
From which orbital in a lithium atom is an electron transferred to form Li ion?
From the second s orbital: Li(1s2, 2s1) --> Li+(1s2, 2s0) + 1e-
What atom that has 3 protons?

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.
Compare the stability of a lithium atom with that of its ion Li plus .?
Li+ means that the atom lost an electron. And this means it has now has a complete outershell, thus being more stable than the Lithium atom with 1 valence electron
When a lithium atom forms a Li plus ion the lithium atom does what?
THe lithoium atom has IONISED ( lost) an electron, to become the lithium ION.
