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
they have few valence electrons and aren't close to having eight valence electrons
Lithium have available for bonding one electron.
Fluorine has 7 valence electrons.
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
Lithium has one valence electron.
One. Lithium is a group1 element
1
There is one valence electron in lithium, also in every other alkali metal element.
Li +
lithium donates an electron to bromine
Boron has 3 valence electrons.Boron has 3 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 have one valence electron
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.
