Sigma (σ) bonds are formed by the end-to-end overlap of atomic orbitals, which is the first bond formed between two atoms. Pi (π) bonds are formed by the side-to-side overlap of atomic orbitals and occur only in addition to a sigma bond, as seen in double bonds like in ethylene (C2H4), where there is one sigma and one pi bond between the carbon atoms.
