Single bond
Single bond
A Single bond (pronunciation: /ˈsɪŋɡəl bɒnd/) is a type of chemical bond that involves the sharing of one pair of electrons between two atoms. This is the simplest type of bond in chemistry.
Etymology
The term "single bond" comes from the fact that only one pair of electrons is shared between atoms. The word "single" is derived from the Old English sengl, meaning "alone" or "one", and "bond" comes from the Old Norse band, meaning "something that binds or confines".
Description
In a single bond, each atom provides one electron that can be shared with another atom. This type of bond is also known as a sigma bond, which is the strongest type of covalent bond. Single bonds are often represented in chemical formulas and structural formulas by a single line between the symbols of the atoms.
