WebCovalent bonds occur when electrons are shared between two atoms. A single covalent bond is when only one pair of electrons is shared between atoms. A sigma bond is the strongest type of covalent bond, in which the atomic orbitals directly overlap between the nuclei of two atoms. WebTranscribed image text: A single bond is generally composed of one π bond. one σ bond. two σ bonds. one π bond and one σ bond.
