Verified step by step guidance1
Understand that chemical bonds form by the overlap of atomic orbitals from different atoms, which allows electrons to be shared or transferred.
Recall that a sigma (\(\sigma\)) bond is formed by the head-on (axial) overlap of orbitals, such as s-s, s-p, or p-p orbitals, along the internuclear axis.
Recognize that a pi (\(\pi\)) bond is formed by the side-by-side (lateral) overlap of two p orbitals, occurring above and below the internuclear axis.
Since the problem states overlap between an s orbital and a p orbital, the overlap is head-on, which corresponds to the formation of a sigma (\(\sigma\)) bond.
Therefore, the bond formed by the overlap of an s orbital and a p orbital from two different atoms is a sigma (\(\sigma\)) bond.
