Sigma in chemistry

In chemistry, sigma bonds (σ bonds) are the strongest type of covalent chemical bond. They are formed by head-on overlapping between atomic orbitals. Sigma bonding is most simply defined for diatomic molecules using the language and tools of symmetry groups. In this formal approach, a σ-bond is symmetrical with respect to rotation about the bond axis. By this definition, common forms of si… WebSix Sigma Black Belt with a BSE in Industrial Engineering and a BS in Chemistry. Previous engineering experience in automotive and healthcare.
