Neither of these metals hold onto their outer electron (singular, as they are alkali metals) very strongly. Relatively speaking though, lithium holds onto its outer-most electron more strongly than Sodium does.
Lithium is an example of an element that has less than 8 electrons. It has 3 electrons in its outer shell.
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
I think lithium should be more reactive as it has only 1 valance electron wheres Boron has 3 valance electrons. The electro positivity(tendency to lose electrons) of Lithium is greater then Boron, therefore more reactive.
if lithium electrons are held in their outer shell by a strong attractive force from the nucleus because it has a much smaller force. The outer electron in lithium is near to the nucleus so therefore it has a quite large force ... what else can i write?
Lithium holds onto its outermost electron more strongly than sodium due to lithium's smaller atomic size and higher nuclear charge. This results in greater attraction between the nucleus and the electron, making it harder for lithium to lose its outer electron compared to sodium.
The z effective of lithium is important in determining its chemical properties because it influences how strongly lithium's outer electrons are attracted to its nucleus. This affects how easily lithium can form bonds with other elements and participate in chemical reactions.

A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
1 - one
Li, Lithium has one electron in its outer shell. Valence electrons occupy the orbits furthest from the nucleus,
Just the one electron in Lithium's outer shell is responsible for its chemical properties.
A lithium atom has one electron on the outer shell. This is because there is 2 electrons maximum on the inner shell, so there is one left over for the outer shell. Hope you understand now xx

Lithium can gain and lose electrons because it has three electrons in its outermost energy level. It can lose one electron to achieve a stable configuration like a noble gas, or gain seven electrons to complete its outer shell. This ability allows lithium to form different ions with different charges.
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
