A bond involving only two valence electrons...


A single bond is a bond in which two atoms share two valence electrons each, forming a covalent bond. It is written usually as #A-A# or #A:A# in Lewis structures. All single bonds are linear. Examples of single bonds include #C-H,H-H,H-F#, and many more, usually involving hydrogen atoms.

Usually, single bonds are sigma bonds, where atomic orbitals overlap each other head-on.
