There is one valence electron in lithium, also in every other alkali metal element.
Francium and lithium have the same number of valence electrons.
Lithium has 1 valence electron.
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.
Boron has 3 valence electrons.Boron has 3 valence electrons.
Lithium has one valence electron.
Lithium has only one valence electron. A valence electron is an unpaired electron available for bonding with other elements. This makes lithium is a highly reactive element that can bond rapidly and often violently with any element having four to seven valence electrons (or with hydrogen).
Both lithium and potassium have one valence electron
Li3N is lithium nitride, an ionic compound. Lithium, being an alkali metal, has 1 valence electron. The "3" subscript means there are 3 of them. Nitrogen is a non-metal with 5 valence electrons. This means it needs 3 more to satisfy the octet rule, which it gets from the 3 lithiums. So, nitrogen's 5 plus lithium's 1 (times 3) = a total of 8 valence electrons.

Argon and Xenon have the same number of valence electrons, both are noble gases (group 18 that have 8 electrons).
To find the number of valence electrons in an atom of a representative element, all you have to do is look at its group number. Ex: Group 1 (Hydrogen, Lithium, Sodium, Potassium, ect.) All have 1 valence electron.
Lithium and Sodium both have 2 valence electrons.
