Germanium Valence Electrons
Why germanium has 4
Germanium has 32 electrons, arranged as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p2. The highest shell is n = 4, holding 4s2 4p2, so 2 + 2 = 4.
Germanium is in group 14; for groups 13–18 subtract 10 from the group number.
What that means for bonding
Four is halfway to an octet, so germanium usually shares electrons rather than gaining or losing them, forming four covalent bonds.
Electrons per shell: 2, 8, 18, 4. See the germanium electron configuration and orbital diagram or the full germanium data sheet.

Germanium valence electrons FAQ
How many valence electrons does germanium have?
Germanium has 4 valence electrons. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p², and the outermost shell (n = 4) holds 4s² + 4p².
How do you find the valence electrons of germanium?
Germanium is in group 14; for groups 13–18 subtract 10 from the group number.
How many bonds does germanium form?
Four is halfway to an octet, so germanium usually shares electrons rather than gaining or losing them, forming four covalent bonds.
What is the Lewis dot structure of germanium?
The symbol Ge with 4 dots around it, one per valence electron, placed singly on each side before any side is paired.
How many core electrons does germanium have?
28: 32 electrons in total minus the 4 valence electrons.
