Understand that chemical bonds form by the overlap of atomic orbitals between atoms.
Recognize that there are different types of covalent bonds based on how orbitals overlap: sigma (σ) bonds and pi (π) bonds.
Recall that a sigma (σ) bond is formed by the end-on (head-to-head) overlap of atomic orbitals along the internuclear axis.
Know that a pi (π) bond is formed by the side-to-side overlap of p orbitals above and below the internuclear axis.
Conclude that the bond formed by end-on overlap of atomic orbitals is a sigma (σ) bond.
