Lithium has 1 valence electron.
Francium and lithium are both alkali metals in group 1 of the periodic table. They have similar chemical properties due to having one electron in their outer energy level, making them both very reactive. However, francium is much more reactive than lithium because it has a larger atomic size and a single electron further from the nucleus, making it easier to lose that electron.
There is one valence electron in lithium, also in every other alkali metal element.
From the second s orbital: Li(1s2, 2s1) --> Li+(1s2, 2s0) + 1e-
Potassium is more reactive than lithium. This is because the reactivity of an alkali metal increases as you move down the group in the periodic table. Potassium is below lithium in the periodic table and has one more electron in its outer shell, making it more readily give up that electron to form compounds.
lithium atom is just a ball it has 1s and 2s orbitals both of which are spheres the 1s is occupied by two electrons and the 2s one electron
Among hydrogen, lithium, and sodium, hydrogen has the smallest atomic radius because it has the fewest number of electron shells and the smallest number of electrons, leading to a smaller atomic size.
Lithium is a metal, it reacts by losing an electron to form a positive ion. It is a member of Group 1 with sodium and potassium.
Based on the atomic number of lithium there are three protons in a lithium atom.

Oh, dude, when fluorine and lithium get together, they form lithium fluoride. It's like when peanut butter and jelly come together to make a sandwich - except in this case, it's a chemical reaction. So yeah, lithium fluoride is the name of the game when these two elements decide to hang out.
Li3P Li is in Group 1, meaning it has 1 valence electron and therefore needs to lose one electron to fulfill the octet rule. P is in Group 5, meaning it has 5 valence electrons and needs to gain three to fulfill the octet rule. Three Li atoms "give" one electron each to one P atom.
