# What particles may be gained, lost, or shared by an atom when it forms a chemical bond?

Dec 14, 2016

None are gained or lost, because that would imply creation or destruction of matter, respectively. Valence electrons of the elements in the bond are shared.

The $\text{gain}$, $\text{loss}$, or $\text{sharing}$ of $\text{electrons}$ occurs in every chemical bond.
