Khan Academy is a nonprofit with the duty of providing one free, world-class education for anyone, anywhere. WebSigma (σ) bonds are strong covalent bonds that occur when atomic orbitals overlap. When the atomic orbitals overlap to create a bond, the electrons are shared creating electron density between the nucleus of each atom. The location of the electron density is the σ bond. A single bond is made of one σ bond.
