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.
Alkali metals have only one electron in the outer shell.
They are monovalent and form cations Me+.
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.
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?
The happy atoms are the noble gases. They don't react because their valence electron shells are full. The goal of every element is to have the most outer shell of electrons full. The first shell holds 2 electrons, and every shell after that holds 8 electrons. So helium and hydrogen both want to have 2 electrons in their outer shells. Elements like neon and argon have 8 electrons in their outer shells. Atoms like chlorine and fluorine have 7 electrons in their outer shells. This means that aren't "happy" because they want to have 8. This is why they ionically bond with atoms like sodium that have 1 electron in their outer shells. Sodium gives that electron to chlorine and now both have 8 electrons in their outer shells.
Atoms do not actually have desires as such, although the metaphor can be useful. Atoms are more stable when they have a full outer electron shell. The smaller atoms, hydrogen, helium, lithium, and beryllium, can obtain a full outer shell with only two electrons in it. The heavier atoms require 8 electrons to have a full outer shell. That is known as the octet rule (an octet is a set of eight).

Li, Lithium has one electron in its outer shell. Valence electrons occupy the orbits furthest from the nucleus,
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.
lithium donates the electron in its outer orbital to fluorine which then has a completed outer shell
A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
Both francium and lithium have 1 electron in their outer electron shell and have a partially filled s-orbital. Both metals easily lose this outer shell electron.
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
hydrogen, helium, lithium, and beryllium
Lithium, Rubidium, Cesium, Francium.
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
