The type of chemical bond characterized by overlapping atoms is a **Covalent Bond**.
In a covalent bond, two atoms share one or more pairs of electrons. This sharing allows each atom to reach a stable electron configuration. The regions of electron density in these bonds can be viewed as "overlapping" between the two atoms.
The overlap of atomic orbitals can be in the form of sigma (σ) or pi (π) bonds. Sigma bonds occur when orbitals overlap along the axis connecting two atomic nuclei, while pi bonds occur when parallel orbitals overlap.
