Lithium Valence Electrons
Why lithium has 1
Lithium has 3 electrons, arranged as 1s2 2s1. The highest shell is n = 2, holding 2s1, so 1.
Lithium is in group 1, and groups 1 and 2 have as many valence electrons as their group number.
What that means for bonding
As a metal, lithium tends to lose valence electrons rather than gain them, forming Li+ ions.
Electrons per shell: 2, 1. See the lithium electron configuration and orbital diagram or the full lithium data sheet.
Same group, same count
Lithium valence electrons FAQ
How many valence electrons does lithium have?
Lithium has 1 valence electron. Its electron configuration is 1s² 2s¹, and the outermost shell (n = 2) holds 2s¹.
How do you find the valence electrons of lithium?
Lithium is in group 1, and groups 1 and 2 have as many valence electrons as their group number.
How many bonds does lithium form?
As a metal, lithium tends to lose valence electrons rather than gain them, forming Li+ ions.
What is the Lewis dot structure of lithium?
The symbol Li with 1 dot around it, one per valence electron, placed singly on each side before any side is paired.
How many core electrons does lithium have?
2: 3 electrons in total minus the 1 valence electron.
