What type of bond involves sharing one pair of electrons?

A single bond involves the sharing of one pair of electrons between two atoms. This type of bond is fundamental in forming covalent compounds, where two nonmetals come together to achieve a more stable electron configuration, often resembling that of noble gases. In a single bond, each atom contributes one electron, resulting in a shared pair that helps hold the atoms together.

In contrast, a double bond consists of two pairs of shared electrons, while a triple bond involves three pairs of shared electrons, making those bonds stronger and shorter than a single bond. An ionic bond, on the other hand, results from the transfer of electrons rather than sharing, leading to the formation of charged ions that attract each other through electrostatic forces.
