A single bond is a type of chemical bond where two atoms share one pair of electrons. This bond is typically represented by a single line (e.g., H—H in hydrogen gas). Single bonds are commonly found in many covalent compounds and are characterized by the following features: 1. **Bonding Electrons**: Each atom contributes one electron to the bond, resulting in a shared pair of electrons that helps hold the two atoms together.
