in modern Periodic Table the elements are arranged in groups according to their valency . valency increases from 1 to 4 and then decreases from 4 to 0. thus as lithium belongs to third group its valency is 3
1
Lithium and Sodium both have 2 valence electrons.
2nd energy level, the electron arrangement is 2,1 at ground state
they have few valence electrons and aren't close to having eight valence electrons
Lithium have available for bonding one electron.
Lithium has 1 valence electron.
Lithium has one valence electron.

Lithium and Sodium both have 2 valence electrons.
There is one valence electron in lithium, also in every other alkali metal element.
Francium and lithium have the same number of valence electrons.
2nd energy level, the electron arrangement is 2,1 at ground state
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.
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 are in Group I of the Periodic Table, so they both have one valence electron.
they have few valence electrons and aren't close to having eight valence electrons
Lithium have available for bonding one electron.
