- And so if you've got an odd number of valence electrons, this whole idea breaks down.
One species is has three valence electrons, the other species has five valence electrons.
- One species is has three valence electrons, the other species has five valence electrons.
Examples
-
Now each of them uses three of their valence electrons to share with hydrogens to make the three XH three bonds.
-
It's it's easy for the valence electron to be given away.
-
However, we've got lots of valence electrons left, right?
-
These electrons, or negatively charged ions, are also called valence electrons, and it is in fluorine's inherent properties that electronegativity is enhanced.

Each atom is covalently bonded to each of its four nearest neighbors; that is, each silicon atom shares its four valence electrons with the four neighboring atoms, forming four covalent bonds.
Academic text (1993) -
In chemical bonds, atoms can either transfer or share their valence electrons.
-
Each element in a group has the same number of valence electrons and typically behaves in a similar manner when bonding with other elements.
-
Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds.

Morphology
The phrase is a straightforward noun–noun composition: 'valence' (the bonding capacity or relevance to combining with other atoms) modifies 'electron' (a negatively charged particle), so a learner who knows both constituent meanings can infer it refers to the electrons involved in bonding. This is a compositional, domain-specific term rather than an idiom, so its meaning is transparently derived from the parts.
Etymology
Valence electron The term valence electron names a valence electron that sits in an atom's 'outer shell'. Because these outer electrons can reach other atoms, they are the ones that 'form bonds' and so decide how atoms join and react.
